“…Panuwet et al [42] analysed the urine samples from a group of school children (207) in Chiang Mai, Thailand aged between 12 to 13 years who were identified as having agricultural and nonagricultural family backgrounds. Spot urine samples were analysed for TCP and 92% had detectable levels.…”

“…The ECID ranged from 30.0 to 1800.0 ng/kg/day (1.4 to 3.2 log scale) with the highest from students in an agricultural environment. Dietary exposure was assumed to be the main pathway of exposure with chlorpyrifos being monitored frequently in dietary components in Thailand [42]. It is interesting to contrast this result with that of children in Costa Rica who live in plantations where bags treated with chlorpyrifos are used to protect fruit.…”

A wide ranging survey was carried out of the available data from ten different countries on human exposure to chlorpyrifos, in many different occupational and nonoccupational settings. Low levels of chlorpyrifos residues were found to be widely distributed in the global human population, but most of these do not constitute a public health risk, as evaluated using the U.S. Environmental Protection Agency (USEPA) Guidelines. For example, the general populations in USA, Germany and Italy had detectable residue levels well below the guidelines. However, high levels of health risk were apparent in a specific group of pregnant mothers in the USA, at median exposure with a HQ 0.50 of 26.6, suggesting that most of this population group was affected. Also the high exposure group (5% most exposed) with occupationally exposed manufacturing workers in the USA had a HQ 0.95 of 2.6 to 42.0, and pest control applicators in Australia and the USA both had a HQ 0.95 of 5.2. Some farmers in Sri Lanka and Vietnam had a high level of risk after spraying applications, having a HQ 0.95 of 2.2 and 19.5 respectively at the high exposure level. These results suggest that there is a possibility of adverse health effects in specific population groups in many different settings throughout the world. OPEN ACCESSToxics 2014, 2 93

“…Although its use in certain applications has been restricted in several countries, producers easily find market in most of the developing and non-developing countries. Low economic price and easy access make public choose chlorpyrifos over the other pesticides (Panuwet et al 2009;Lu 2011;MunozQuezada et al 2012;Murphy et al 2012;Phung et al 2012). It was reported as one among the most commonly used organophosphate pesticide in the USA in 2007, with an estimated 7-9 million pounds applied (Grube et al 2011).…”

Chlorpyrifos: pollution and remediation

2015

View full text Add to dashboard Cite

The widespread use of pesticides in modern agriculture is of increasing concern due to environmental contamination and subsequent biodiversity loss. Chlorpyrifos is a toxic organophosphate pesticide. Repeated applications of chlorpyrifos modify the soil microbial community structure and pose potential health risks to the other nontargets. Chlorpyrifos has been reported as the second most commonly detected pesticide in food and water. Extensive use of chlorpyrifos in agriculture and persistence in the environment have raised public concern and demand for safe technologies to overcome the pollution and toxicity problems. Here, we review pollution and toxicity issues associated with chlorpyrifos use and discuss strategies to solve pesticide contamination. Chlorpyrifos, previously shown to be resistant to enhanced degradation, has now been proved to undergo enhanced microbe-mediated decay. Here, special emphasis is given to degradation methods such as ozonation, Fenton treatment, photodegradation, and advanced oxidation processes along with microbial degradation. Finally, we focus on degradation process at enzyme and molecular levels which will enable us to elucidate the exact degradative pathway involved in biodegradation.

A sensitive, simple and rapid QuEChERS extraction method and liquid chromatography equipped with triple quadrupole mass spectrometry (LC-MS/MS) were used to determine 42 pesticides in dates. Acidified acetonitrile and citrate buffer salts were used to extract re-hydrated samples. Acceptable validation performances were achieved, i.e. recovery range of 70-120% and RSD values ≤20% for 42 analytes at three different concentrations:100, 50 and 10 μg/kg. This method was used to analyse 200 date fruit samples (var. Sukkari) collected from different large markets in the Al-Qassim region in Saudi Arabia. Pesticide residues were detected in 36 (18%) of the date fruits samples, and 15 samples (7.5%) exceeded the maximum residue levels. The ruggedness test results showed that this method is robust and suitable for the determination of pesticide residues in dates. Additionally, the results showed that the monitored dates did not have a health impact on consumers in Saudi Arabia during the study period.
