While the dangers of mixing benzodiazepines and heroin/other opioids are well documented, there is a paucity of data regarding concomitant NMU of benzodiazepines and stimulant drugs, or NMU of Z-drugs and opioids, and, given the prevalence of these combinations, this requires further investigation.Background The use of pesticides during tea plant cultivation support agricultural production and prevents and controls pests, diseases, and weeds. It is of the utmost importance to balance pesticide application with tea quality, safety, and consumer health. The uptake of pesticides into plants may lead to the presence of residues that are hazardous to human health, especially for some foliar-applied insecticides. The movability or penetration behavior of the pesticide remains unknown after it was sprayed on tea leaf. Results Two organophosphate (acephate, trichlorfon) and three neonicotinoid pesticides (imidacloprid, thiamethoxam and acetamiprid) on treated fresh leaf of tea saplings were verified that they can be removed with washing in the phytotron. Four targets have little penetrative ability into tea leaves, mainly existing (>92%) on the tea leaf surface except for trichlorfon (>70%) in 30 days. With higher vapor pressures, trichlorfon and acetamiprid had relatively higher penetration ratios, of 8.63-29.60% and 0.28-8.03% respectively. Two organophosphate insecticides were further found to degrade more quickly, with lower final amounts of residues on and in the whole leaf than the neonicotinoid pesticides. In field test, these residues could be reduced for 45-72% after pre-harvest interval (PHI, 3 days), 16-89% (7 days) when the fresh tea shoots were sprayed with 2 or 4 L/m-2 of water. Conclusions The pesticides with different structures have the different penetration abilities on the tea leaf surface, and some pesticides in commercial tea
