Background:
This study determined the fluoride content of green tea from various parts of Asia, where green tea originates.
Methods
We brewed 2.5 g each of 4 types of green tea (from China, South Korea, Japan and Sri Lanka) using deionized water heated to boiling. Water was cooled to 71°C, then tea was steeped for 2 minutes. This process was repeated 20 times, thus providing 20 samples for each tea type. In addition, 20 control samples of deionized water were brewed to the same specificati

Highlights
Evidence of poisoning with organophosphorus (OP) nerve agents requires biomedical verification.
OP nerve agents undergo common biotransformation pathways producing valuable biomarkers.
Internationally accepted methods target remaining poison, hydrolysis products and protein-adducts.
Mass spectrometry-based methods provide optimum selectivity and sensitivity for identification.
Methods, strategies, current proceedings, quality criteria and real cases of poisoning a

Introduction
Environmental neurotoxicants are pollutants that can negatively affect many cellular metabolic-processes through different pathways: neuroendocrine/thyroid hormone disruption (Pb, methyl-Hg, organochlorines, and polychlorinated biphenyls-PCB), oxidative stress (Pb, methyl-Hg, organochlorines, and chlorpyrifos), dopamine dysfunction (Pb, methyl-Hg, As, chlorpyrifos, pyrethroids, and organochlorines) (Heyer and Meredith, 2017; Rock and Patisaul, 2018).

Abstract
Fluorine has many beneficial features and applications but can cause toxicity at high doses. Herein,
we describe its chemical properties and benefits to agrochemical design as well as potential metabolic
liabilities and exposure assessment in vivo.
The use of fluorine in drugs and agricultural chemicals has greatly expanded since the first fluoro compound, fludrocortisone, was approved in 1955. In 2018–2019, 45% of small molecule drugs approved by the U.S.
