“…Chlorpyrifos is an organophosphate pesticide introduced in 1965 by Dow Chemical Company. It has other trade name such as Brodan, Detmol UA, Dowco 179, Dursban, Eradex, Lorsban, Piridane, Stipend which kills various pests in which insects and worms are inclusive [4]. It is used on crops, animals, and building [4].…”

Nigeria is currently the largest rice producing country in Africa. High volumes of waste such as rice husk are inevitable with high production. Also pesticides used to rid of pests, diseases and improve crop yield find their ways into available surface water that serves domestic purpose. This study therefore determined the efficiency of conventional water treatment procedure for pesticide/pesticide residue removal and evaluated the performance of rice husk-based biochar as adsorbent to remove chlorpyrifos from domestic water supply with a view to manage solid waste (rice husk) for treating pesticide polluted water. Batch adsorption studies were carried out to assess the adsorption efficiency of rice husk biochar (RHB) for chlorpyrifos pesticide removal from surface water. Adsorbent dosage, initial concentration, contact time and dosage were optimized during simulation experiment. RHB and commercial activated carbon (CAC) were used for the removal of chlorpyrifos from surface water sample using the optimum condition from the simulation experiment after which the concentrations were determined using Gas Chromatography with Mass Spectrometry detector. Both Langmuir and Freundlich adsorption isotherms were investigated. RHB gave percentage moisture (5.27±0.94), carbon yield (39.44±0.47), ash (41.96±0.96), fixed carbon (35.24±0.55), volatile matter (35.67±1.01 mg/g), Iodine number (85.57±0.81), surface area (97.20 m2/g), pH (7.90±0.14) and Electrical conductivity (298.8±1.14). Of the elements present in the char, Carbon has the highest percentage of 59.14%. Best adsorption conditions for RHB in this study were 2.8 mg/L initial concentration; 0.8 g of adsorbent dosage; pH of 5 and contact time of 30 min. The data fitted Freundlich than Langmuir model (R2 0.996 and 0.8315 respectively). Percentage removal of chlorpyrifos for CAC and RHB was 93.7±3.96 and 94.5±5.23 respectively for the surface water sample. Results concluded that RHB was efficient for removal of chlorpyrifos present in water and could be used as alternative for CAC in water treatments.

A 25 years old woman who ate her birthday cake, which was brought by her husband. After consumption of cake she felt some illness like irritation in chest and vomiting, so she was brought to hospital for treatment and doctors collected her gastric lavage during treatment. Chemical analysis of cake sample by thin layer chromatography and Gas chromatography-mass spectroscopy (GC-MS) revealed organophosphorus insecticide chlorpyrifos and pyrethroid insecticide cypermethrin, which confirmed intention of accused to cause health hazard to victim which may lead to homicide.

“…В організмі людини і тварин хлорпірифос в результаті десульфурації за участю цитохрому Р-450 печінки (CYP2B6) біоактивується на два основних біологічно активних метаболіти -хлорпірифос оксон і 3,5,6-трихлор-2-піридилфосфат [11][12][13][14][15]. Хлорпірифос оксон може зв'язуватись з ацетилхолінестеразою та призводити до зниження її активності, викликаючи холінергічну гіперстимуляцію нервової і м'язової систем [11,[16][17][18]. За впливом на нервову систему хлорпірифос оксон більше ніж у 3000 разів активніший ніж хлорпірифос [19].…”

Objective. Analyse and summarize modern data on the degree of hazard of chlorpyrifos when used in accordance with the intended purpose, substantiate the expediency of limiting the scope and extent of use of insecticide in the human living environment. Materials and methods. Analytical review of scientific publications has been performed using the abstract database of libraries and the text database of medical and biological publications PubMed. Results. Based on the conducted analytical review of scientific publications, data on the degree of hazard of chlorpyrifos have been summarized, the requirements regarding the expediency of the prohibition of the use of chlorpyrifos and chlorpyrifos-based preparations as insecticidal agents in the human living environment, first of all, in everyday life, in maternity departments, in medical institutions, in child day care centres and educational institutions have been substantiated.
