I know an Iranian in the Netherlands who says the tea there is mostly coloring.
Chinese tea is again a whole different world from Indian tea, and has a much broader spectrum of complexity. You could spend a lifetime learning about Chinese tea.
Different countries do buy different types and qualities of tea. The US is big market for low quality (dust, stalks) tea for tea bags.
Countries that like strong sweet tea with lots of milk buy tea that is low grown (i.e. lower elevations) and processed using the "cut, torn curled" process rather than the older "orthodox" process. High grown (on mountains) tea is better for those who drink it without milk.
Leaves do tend to be higher quality and they have grades reflecting the size of the pieces. There is a standard system which is marked on some types of tea.
It is usual to pluck two leaves and a bud. Plucking more would add a lot of stalk which lower quality. Plucking or using just a bud produces a very delicate flavour (sivlertips). High grown silvertips is good with
Most tea is blended so will contain a mix of different things.
You’re gunna want to look at the later half of that.
there's an extensive body of research on synthetics having no effect on human health, from goverment funded, private and independent research... if you access your country's official institution you'll see there's plenty of synthetics allowed in organic agriculture just because they mimic perfectly "organic" substances
interesting point too, is the lack of any extensive meta-analysis/studies on organic pesticide impact on health and plus the fact organic farm is rather poor (produce less than 2% of the global food) and usually if not always lack good machinery to spread pesticides on the recommended quantities science points out (which organic agriculture also has less literature on that too)
Why were they allowed in the first place, if "research" was enough? Science is not definitive, and what we believe to be an approximation of the truth today way be discovered to be totally wrong tomorrow. You are confusing science and religion.
Would you defend, for instance, that DDT and other organochlorine poisons are safe? They were the darling of scientists and agrobiz companies for a long time, until we discovered well that they were dangerous.
Of course, if we find a strict equivalent to a biopesticide that happens to be synthetical, it would be a good substitute. But most synthetic pesticides are not like this, unfortunately.
And what you say about the lack of studies regarding organic farming is a plain lie, it takes 30 seconds on google scholar to find it:
- Farmers in organic farms are less exposed to health effects of synthetic pesticides: https://www.sciencedirect.com/science/article/abs/pii/S03784...
- Organic farming improve soils and yields: https://www.sciencedirect.com/science/article/pii/S1658077X2...
- Review on organic food quality and health effects: https://link.springer.com/content/pdf/10.1186/s12940-017-031...
as many synthetic are developed... last time i was making an inventory of an exclusive corn and soybean high tech farm (selling on the hundreds millions USD) there was at least 45 different pesticides... some were distributed in a quantity of 10 mililiters! per hectare with machine with proper air filter at the cabine of the tractor never seen by the organic movement, which by the way, considering their ~ 30% increase in land, fertilizers and pesticides needs and their production totalling less than 2% of all the global food, feels quite a stretch to read author's conclusion of your last study...
your 2° cited study shows improvement on soil quality by variety/rotation, what it has to do with GMO technology? one literally can plant varied stuff while using synthetic pesticides... take a look on most health studies done in organics and health not controlling for life style factors, nor any major study even found dangerous levels of pesticides in food. don't get me wrong, there are niche cases were organic crops just make sense but when you start dismissing GMO technology for a 8 billion and growing world, which in decades will move out of the rural ambient (rural flight is an on going thing, literally no one wants to work in farms, much less in organic ones were the workload is much bigger, if not borderline on slavery (trust me, i did some WWOOF)), feels pure ignorancy out of greenwashing or small studies compared to what we rolled on science the past 30 years of GMO technology

Why are you trying to slide the discussion with GMOs, which aren't relevant since we talk about pesticides?
Saying that "organic has 2% of the world crop" is not true : certified organic crops, yes. Most of the earth's biomass grows without synthetic pesticides, and many farms in the world have the same practices without the labels.
In general, organic farming is a reference, of course that it doesn't have to be a religion. It is also a great source of scientific experimentation, especially for soil regeneration and biodiversity (which alas, I know, isn't profitable for Monsanto&co... yet!)
Using less pesticides in general is something that is proven better[1], and doesn't necessarily reduces yields[2]. Organic farming is part of the global effort for the reduction in pesticide usage, and doesn't have to be hegemonic. Having "organic farming only" areas are for instance great to create havens for biodiversity, while agricorps are allowed to run wild elsewhere.
Overall it's great for consumer choice, and reducing to the maximum pesticides intake for children should be a goal, given their sensitivity to endocrine disruptors.

"Organic" as in certified 'Organic' or as in the class of molecules?
If the former then I'd love to see the classification requirements that make a qualifying chemical safer all the ones that aren't.
If the later, that's blatantly untrue
Note that other countries may have different legislations. You are also free to eat DDT to prove that organic farming is not really safer.
Honestly curious, which of these is more harmful than the non-organic alternatives?

This dichotomy underpins a difference in regulation between the USA and Europe. As mentioned already, the EU Commission applies the "precautionary principle" in its legal regime for food and chemicals. This is not "unscientific". Empiricism has been more popular in the Anglophone world, but rationalism was one of the pillars of the scientific Enlightenment.

So I always make a point to buy the inorganic one (pun intended!).
Organic is marketing. Organic produce is more profitable.
In the UK, tea means tea bags and that normally means tea bags made of a plastic/paper mix. If I remember, the bag material is made and then they heat it up to get the plastic out, revealing the holes, needed for the bag.
Of late there has been criticism of microplastics in tea bags, and the posh organic bags have fared quite badly. Fancy sachets are not necessarily it.
As for chemicals, not one farmer spends any money than what is the bare minimum, no matter what they do. They might have to put all kinds of toxic chemicals on crops but they are not going to waste money over-doing it, because they are tight with the money, at all times, under all circumstances.
So the question has to be asked, is it worth worrying about the worrying levels of chemicals in tea when there are worrying levels of microplastics that the body really cannot get rid of with some liver-fu?
But, are there more toxins? The working class British way to have tea is with milk and two sugars. The milk is designed for baby cows, not grown men, they should be 'weaned off' because there are all kinds of things in dairy that might not be toxins, but could be considered to be. For example the cholesterol and saturated fat. Next the sugar, which is fine in moderation, so long as you don't care for your teeth, and, when combined with saturated fat, can contribute to type two diabetes.
Clearly opinions vary regarding the health aspects of milk and sugar in tea, my grandmother almost made it to a century, consuming plenty. However, you can reduce the toxic load from drinking tea by getting rid of the microplastics by using plant-based teabags (even LIDL have them), not having milk and sugar in the tea and, only then, getting concerned about buying organic.
Organic does not mean no nasty chemicals, it means no synthetic nasty chemicals. However, it is still a good nice-to-have, but, realistically, if you want to cut your exposure to toxins, there are these other huge areas that are under our control, but those things are going to be controversial lifestyle choices. Just not using cars 'could' reduce your toxic load far more than any organic teabag.
https://en.wikipedia.org/wiki/Saturated_fat
> A 2024 meta-analysis found that odd-chain and longer-chain saturated fatty acids were negatively associated with the risk of cardiovascular disease, including stroke.
https://en.wikipedia.org/wiki/Odd-chain_fatty_acid
>OCFAs are found particularly in ruminant fat and milk (e.g. pentadecylic acid).
(I don't know if that means most of the saturated fatty acids in milk, it's full of different varieties.)
With saturated fat the health authorities that have science but industry lobbying to content with, have told us to avoid the stuff because it clogs the arteries and invariably comes with cholesterol because animals. Arguably Ebola and AIDS are worse than a bit of saturated fat, however, it is a clear message, up there with 'smoking is bad'. Yet a vocal minority will spin this yarn about how wonderful saturated fat is. They are for real and tell the gym-going public all kinds of nonsense.
Yet a diet from before farmers started using copious amounts of synthetic chemicals placed saturated fat as very hard to get. There is no fat on wild animals, only on fattened up farm animals (and humans).
In these former times, meat of any kind was hard to come by. Chicken was saved up for, paying in installments for that special birthday treat. Meat such as rabbit was far more prevalent, the chicken was there for the eggs, not to be eaten as a snack in a lunchtime sandwich.
Hence, scale back all the modern day junk to the idealised peasant diet and there is no need to know anything about any modern day diet or nutrition talking points.
