Mast cells were treated with suspensions of PM2.5 in Dulbecco’s modified Eagle’s medium at concentrations from 25 to 200 mg/L in the absence or presence of 10 mmol/L N-acetyl-L-cysteine. Biological effects and mitochondrial function were assessed by determining cell viability, β-hexosaminidase release, interleukin-4 secretion, reactive oxygen species generation, adenosine triphosphate production, potential alteration of mitochondrial membrane, and activities of mitochondrial electron transport chain complexes I and III. Exposure of mast cells to PM2.5 induced reduction of adenosine triphosphate production, collapse of mitochondrial membrane potential, and inhibition of the activity of complex III. Co-treatment of mast cells exposed to PM2.5 with N-acetyl-L-cysteine attenuated cytotoxicity and the production of reactive oxygen species, and decreased the release of β-hexosaminidase and interleukin-4. Evidently, PM2.5-induced oxidative stress plays an essential role in mitochondrial toxicity and mast cell activation.","PeriodicalId":23210,"journal":{"name":"Toxicological & Environmental Chemistry","volume":"13 1","pages":"170 - 185"},"PeriodicalIF":0.0,"publicationDate":"2020-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78390943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The trace elements (iron, cadmium, arsenic, chromium, lead, boron, nickel, cobalt, tin, copper and zinc) in the particulate matter-10 were found in the range 0.001–0.175 µg m−3. The human health risk assessment has done based on the United States Environmental Protection Agency prescription. The hazard quotient and hazard index values using charcoal, kerosene and electricity stoves were found below 1. This result showed that the inhabitants stay at any of these three microenvironments has no likelihood to have non-cancer health problems. In addition, the life time cancer values for all trace elements were below the tolerable range set by United States Environmental Protection Agency, except chromium, cadmium and arsenic which were found within the tolerable range. Furthermore, the total sum of eleven determined elements was calculated, and the highest concentration was observed using kerosene stove followed by charcoal and electricity stoves, respectively. The use of kerosene and charcoal stove were not the recommended stove as compared to electricity stove for the cooking of Wot.","PeriodicalId":23210,"journal":{"name":"Toxicological & Environmental Chemistry","volume":"6 1","pages":"151 - 169"},"PeriodicalIF":0.0,"publicationDate":"2020-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79146303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fruit water and ethanol extract of C. colocynthis were concentrated for larvicidal and repellent activities on human volunteer against An. stephensi. The temephos larvicide was tested as the positive control. A concentration of 300 mg/L had full-scale mortality and the most toxic effect. The LC50 and LC90 values of C. colocynthis water and ethanol extracts were 180and 283 mg/L, respectively. The LC50 and LC90 values of temephos were 0.2706 and 1.6932 mg/L, respectively. The ED50 and ED90 values of the plant extract were 0.2 and 1.3 mg/cm2, respectively. Thin sections from treated larvae exhibited gross histopathologic effects of C. colocynthis fruit extracts on gut epithelial cell layer by vacuolization of foregut cuboidal and midgut columnar cells. This study suggested that the fruit extracts of C. colocynthis had significant larvicidal and repellent activity to be used as an ideal approach to control the malaria vector mosquito.","PeriodicalId":23210,"journal":{"name":"Toxicological & Environmental Chemistry","volume":"43 2 1","pages":"104 - 92"},"PeriodicalIF":0.0,"publicationDate":"2020-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90930530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
