Monitoring of Pesticide Residues in Commonly Used Fruits and Vegetables in Kuwait

International Journal of Environmental Research and Public Health, Journal Year: 2017, Volume and Issue: 14(8), P. 833 - 833

Published: July 25, 2017

The presence of pesticide residues in primary and derived agricultural products raises serious health concerns for consumers. aim this study was to assess the level commonly consumed fruits vegetables Kuwait. A total 150 samples different fresh were analyzed 34 pesticides using quick easy cheap effective rugged safe (QuEChERS) multi-residue extraction, followed by gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass (LC-MS/MS). Pesticide above maximum residue limits (MRL) detected 21% 79% had no surveyed contained below MRL. Multiple present 40% with two four pesticides, contaminated more than residues. Of investigated, 16 detected, which imidacloprid, deltamethrin, cypermethrin, malathion, acetamiprid, monocrotophos, chlorpyrifos-methyl, diazinon exceeded their MRLs. Aldrin, an organochlorine pesticide, one apple sample, results indicate occurrence Kuwait, pointed urgent need develop comprehensive intervention measures reduce potential risk regular monitoring sensitization farmers better safety practices, especially adhere recommended pre-harvest intervals is recommended.

A review of chemical and microbial contamination in food: What are the threats to a circular food system?

Environmental Research, Journal Year: 2020, Volume and Issue: 194, P. 110635 - 110635

Published: Dec. 31, 2020

A circular food system is one in which waste processed to recover plant nutrients and returned the soil enable production of more food, rather than being diverted landfill or incineration. The approach may be used reduce energy water use contribute sustainability system. Anaerobic digestion composting are common treatment technologies stabilize produce residual materials that can replenish soil, thus contributing a This only deemed safe feasible, however, if uncontaminated any contaminants destroyed during treatment. review brings together information on several contaminant classes at different stages supply chain, their possible sources, fates digestion. main aim identify factors could impede transition towards safe, reliable efficient We investigated heavy metals, halogenated organic compounds, foodborne pathogens antibiotic resistance genes (ARGs) composting. Production processing were identified as major entry points for these contaminants. Heavy metals pose less risk organics resistance. Given diversity properties among there conflicting evidence about fate There relatively few studies ARGs treatment, have produced variable results, indicating need research clarify final products. Repeated land application contaminated residuals increase accumulation jeopardize safety Thus, careful management into needed.

Consumption of freshwater fish: A variable but significant risk factor for PFOS exposure

Environmental Research, Journal Year: 2020, Volume and Issue: 192, P. 110284 - 110284

Published: Oct. 3, 2020

PFOS, PFOA, PFNA and PFHxS are the PFAS substances that currently contribute most to human exposure, in 2020 European Food Safety Authority (EFSA) presented a draft opinion on tolerable intake of 8 ng/kg/week for sum these four (equaling 0.42 μg/kg if expressed as an annual dose). Diet is usually dominating exposure pathway, particular PFOS has been shown be strongly related consumption fish seafood. Those who eat freshwater may especially at risk since its biota typically display higher concentrations than marine systems. In this study, we estimated range among average Swedish "normal" "high" consumers fish. By mean persons weight average-sized portions. The "normal consumers" were assumed 3 times per year, "high once week. Under assumptions, yearly reached when equals 59 3.4 μg kg meat.
