Carcinogenic Effects

Organochlorine pesticides (OCPs) including Hexachlorocyclohexanes (HCHs) and dichlorodiphenyltrichloroethanes (DDTs) in surface water of Lake Baiyangdian were determined to assess the potential health risk when using as drinking water for children and adults. The concentration of HCHs and DDTs in surface water were in the range of 2.74-11.50 ng L-1 and 3.48-16.88 ng L-1, respectively. Compared with similar results reported around the world, the level of OCPs in this study was in the mid-range. The analysis of health risk indicated that risks from OCPs in most part of the lake would not be risky to human health according to the acceptable risk level, while carcinogenic effects caused by α-HCH might occur if drinking water from Nanliuzhuang (NLZ) and Laowangdian (SCD). α-HCH and β-HCH were the dominating factors for carcinogenic and non-carcinogenic risks, respectively. Risks of OCPs for children were much higher than those caused by OCPs for adults.

Background: Rice is the most important agricultural crop and the main food in Gilan and Mazandaran Provinces in northern Iran where organophosphorus pesticides, especially diazinon, are used. The excessive use of this insecticide in the paddy fields of Rasht County is a serious threat to people’s health. Methods: In this study, 30 rice samples were collected from five zones in the paddy fields of Rasht in summer. The samples were analyzed when rice is sold to assess the health risk caused by diazinon residues in rice. Following the digestion process, the samples were injected into a High-Performance Liquid Chromatography (HPLC) instrument. Analysis of Variance (ANOVA) and one-sample t-test were respectively used for analyzing data and the Health Risk Index (HRI) for assessing the risk of rice consumption. Results: According to the results, the mean residual diazinon concentration in the rice crops of the five studied zones at the time of consumption (three months after harvest) was 0.4±0.43 mg/kg-1. This was higher than the Iranian standard for permissible diazinon concentration in rice. The results of the health risk assessment for rice consumption indicated an HRI value of 0.13 for rice consumption, which did not constitute a serious risk for people who consume rice regularly. Conclusion: Although the results of this study showed that there are no potential health risks for consumers, with increasing the use of chemical pesticides for crops, to achieve food safety, regular monitoring of pesticide residues in crops is recommended

Organochlorine pesticides (OCPs) are chlorinated hydrocarbons that used extensively in the last century for agricultural purposes. Excess use of OCPs results pesticide residues accumulation in the water and fishes and causes various health problems. The concentrations of Organochlorine pesticides (OCPs) residues in water and fish samples of six most contaminated rivers surrounding Dhaka, Bangladesh namely Buriganga, Turag, Balu, Sitalakhya, Bangshai and Dhaleswari were determined and assessed the possible health risks through consumption of accumulated OCPs in fishes from those rivers. .As we know, OCPs are non-biodegradable and thus remain in the environment as pollutants. Therefore, OCPs exposure must be monitored and controlled to reduce the human health risks. Risk assessment is an important procedure to quantify the potential health risks and provides information the risk managers to control the overuse of OCPs. The concentrations of OCPs residues were determined by Gas Chromatography tandem Mass Spectrometry (GC-MS/MS). After sample collection, sample was extracted and analyzed according to the validated method. Several OCPs residues including Aldrin, p,p-DDE, Eldrine ketone, p,p-DDD, Endrin, α-Endosulfan, Heptachlorepoxide, p,p-DDT, Endosulfan sulfate and β-Endosulfan were detected in river water and residues including Aldrin, p,p-DDE, Heptachlorepoxide, p,p-DDD, Endrin and p,p-DDT were detected in fish samples. The Health risk index (HI) values of Aldrin, p,p-DDE, Heptachlorepoxide, p,p-DDD, Endrin and p,p-DDT from analyzed three fish species (Acanthobrama microlepis, Barbonymus gonionotus and Batasio tengana) were ranged from 0.036 to 1.696, 0.029 to 2.007, 0.022 to 1.117, 0.0231 to 0.721, 0.019 to 1.597 and 0.019 to 1.205 for Buriganga, Turag, Balu, Sitalakhya, Bangshai and Dhaleswari rivers respectively. OCPs are quantified in river water and fish samples and potential health risks are accessed. This study suggested that, there might have OCPs mediated health risks through long term exposure of OCPs residues from fishes of those polluted rivers. Although, our study provided estimation about the presence of OCPs in water and fishes from six contaminated rivers surrounding Dhaka city but, further studies are suggested to ensure the safety of peoples.

Heavy metal pollution of soils is a major concern today because contamination of food chain considered as one of the major environmental pathways of human exposure leading to potential health risk.A pot experiment was carried out to investigate the transfer of Zn, Cu, Ni, Fe, Cd, Cr, Pb and Mn from non-contaminated and contaminated soils to jute leaves vegetable plant and to evaluate their associated health risk in the local population.The mean concentration of the heavy metals in jute leaves vegetable plants followed a decreasing order of Fe>Zn>Mn>Cu>Cr>Pb>Cd>Ni. Among the all heavy metals the highest transfer factor (TF) values was found for Cu (77.50-34.95) and the lowest TF value was observed for Ni(0-0.001) in jute leaves vegetables plant. The daily intake of metals (DIM) for a person through ingestion of jute leaves were in order of Fe>Mn>Zn>Cu>Cr>Pb>Ni>Cd. The values of health risk index (HRI) for the heavy metals were less than 1, therefore, no significant health risk is anticipated for the local consumers through ingestion of jute leaves.

ABSTRACTAs the largest industrial and population centre in China, the Pearl River Delta is facing a growing threat of heavy metal pollution from local mining and power industries. This study investigates the distribution and potential health risks of copper (Cu), cadmium (Cd), lead (Pb) and zinc (Zn) in paddy soils and rice at four typical sites. The Nemerow synthetic pollution index (PN) of soils from Fogang, Dabao Mountain, Shaoguan and Lechang were 8.40, 9.10, 4.64 and 10.28, respectively, indicating serious pollution at all four sampling sites. The average concentrations of Cu, Cd, Pb and Zn in rice grains were 2.23, 10.98, 29.84 and 1.62 times their corresponding maximum allowable levels, indicating potential health risks to humans. Cd has greater bioavailability because of its high mobility from soil to roots, and its subsequent transfer to grains. Pb mainly accumulates in roots because of its lower translocation rate from roots to grains. The greatest health risk index for Cd and Pb for adults and children was at the Shaoguan site, probably due to pollution from atmospheric deposition. Cd and Pb had greater health risk indices than Cu and Zn at almost all sites, indicating a major health risk to local people.

AbstractLevels of organochlorine pesticides (OCPs) residues in tilapia fish and their health risk associated with the consumption of fish from Edko lake, Egypt were determined. The quick, easy, cheap, effective, rugged, and safe method (QuEChERS) was used for extraction and clean-up of 18 OCPs residues from fish followed by GC-ECD and GC-ITD analytical tools were employed for identification of OPs. Out of the 18 OCPs, only heptachlorepoxide, p,p-DDE, dieldrin, p,p-DDD, and endrin ketone were detected in muscles of fish with concentrations of 0.1144, 0.2119, 0.4352, 0.1196, and 0.1323 µg/Kg bw, respectively. Results of the risk assessment calculations showed that dieldrin had a health risk index of more than one. This means that there was a health risk to adults associated with the consumption of fish. On the other hand, heptachlorepoxide, p,p-DDE, p,p-DDD, and endrin ketone did not show any direct health risk. Contamination of fish, collected from Edko lake in Egypt, with residues of OCPs might pose health implications if fish were consumed fresh.
