Embryotoxicity of Five Cytostatics in Fathead Minnow ( Pimephales promelas ) Larvae Bull. Environ. Contam. Toxicol. (IF 1.657) Pub Date : 2021-03-13 M. Lefebvre-Raine, N. Paquet, G. Triffault-Bouchet, V. S. Langlois
Cytostatics are compounds used in chemotherapy, known to be genotoxic, mutagenic, and teratogenic at low concentrations. The amount of cytostatic drugs prescribed increases every year as does their release into the aquatic ecosystems, which possibly is a major concern for the health of aquatic organisms. This study aimed to evaluate the putative toxicity of five cytostatics to fathead minnow (Pimephales

Clothianidin in the Tropical Sugarcane Ecosystem: Soil Persistence and Environmental Risk Assessment Under Different Organic Manuring Bull. Environ. Contam. Toxicol. (IF 1.657) Pub Date : 2021-03-12 T. Ramasubramanian
Clothianidin is drenched at planting to manage the termites of sugarcane. The application of organic manures at planting is also in vogue to conserve the soil moisture in the tropical ecosystem. Hence, the persistence behaviour of clothianidin was studied in the sandy clay loam soil of tropical sugarcane ecosystem under different organic manuring. The clothianidin residues persisted up to 90th DAT

The aquatic environment is constantly exposed to chemical pollutants from agriculture and the urban environment. In this study, the effects of Bisphenol A, Naphthalene, and Butachlor on metabolic and antioxidant enzymes of goldfish were investigated during subacute exposure. The samples (n = 144, 100.97 ± 31.47 g) were distributed randomly in 12 glass aquaria (70 L) with a stocking density of 12 fish

Modified Oyster Waste Shells as a Value-Added Sorbent for Lead Removal from Water Bull. Environ. Contam. Toxicol. (IF 1.657) Pub Date : 2021-03-11 Woohang Kim, Rekha Singh
Used oyster shells are considered a waste product of the seafood industry. Herein, we hypothesize that oyster shells can be used as a raw ingredient to synthesize effective sorbents. This study investigated the lead sorption ability of modified oyster shells [phosphoric-acid treated oyster shell (POS) and oyster shells with phosphoric acid (OS + P)] from water. XRD confirmed the presence of calcium

From Past Use to Present Effects: Total Mercury in Crustaceans and Fish in the Inner Estuary of Paraíba do Sul River, Southeast Brazil Bull. Environ. Contam. Toxicol. (IF 1.657) Pub Date : 2021-03-11 Ana Paula Madeira Di Beneditto, Helena do Amaral Kehrig, Inácio Abreu Pestana
Total mercury (Hg) concentration and stable isotope ratios (δ13C and δ15N) were used as chemical tracers in two crustaceans and four fish species that are targets of subsistence fishery in the inner estuary of the Paraíba do Sul River. This fluvial environment in southeast Brazil has a large historical utilization of Hg. δ15N was a better predictor of Hg concentration in the muscle (edible part) than

Non-target Impact of Dinotefuran and Azoxystrobin on Soil Bacterial Community and Nitrification Bull. Environ. Contam. Toxicol. (IF 1.657) Pub Date : 2021-03-09 Taku Yamaguchi, Ahmad Mahmood, Takahide Ito, Ryota Kataoka
Pesticides to protect crops from pests are subject to rigorous risk assessment before registration in Japan. However, further information needs to be collected regarding the assessment of impacts on the natural environment. In particular, nitrifying bacteria play a role in converting ammonium salts to nitrates in soil. However, there is limited research covering the effects of insecticides on nitrification

Identification of a New Potential Cd-Accumulator Pterocypsela indica (L.) Shih Bull. Environ. Contam. Toxicol. (IF 1.657) Pub Date : 2021-03-08 Xingfeng Zhang, Chishan Wu, Xiaoqi Nie, Bo Gao
Three experiments were conducted to investigate the Cd tolerance and accumulation ability of a forage grass, Pterocypsela indica. P. indica accumulated 31.40 and 69.68 mg/kg Cd in roots and shoots, respectively, and plant biomass was unaffected by soil Cd as high as 50 mg/kg. Cd pollution obviously increased the Cd content of the cell wall fraction and decreased that of the soluble fraction in plant

Assessment on the Coupling Effects of Drip Irrigation and Se-Enriched Organic Fertilization in Tomato Based on Improved Entropy Weight Coefficient Model Bull. Environ. Contam. Toxicol. (IF 1.657) Pub Date : 2021-03-08 Wei Huang, Yulin Zhu, Daobo Wang, Ning Wu
Selenium (Se) is an essential micronutrient for human beings and plants are the current main sources of Se element in Asian diet. Therefore a feasible way to increase people’s Se intake is to increase Se content in plants. In this paper, we focus on how the tomato (Solanum Lycopersicum) yield and quality are influenced by the effect of irrigation amount, Se-enriched and high-calcium organic fertilizer

The Differential Effects of Salinity Level on Chlorpyrifos and Imidacloprid Toxicity to an Estuarine Amphipod Bull. Environ. Contam. Toxicol. (IF 1.657) Pub Date : 2021-03-01 Kyle M. Knysh, Simon C. Courtenay, Carissa M. Grove, Michael R. van den Heuvel
Agricultural activity within coastal watersheds results in estuaries becoming the receiving environment for pesticide inputs. In estuaries, salinity can alter insecticide responses of exposed crustaceans. The acute toxicity of environmentally relevant doses of chlorpyrifos and imidacloprid were examined using the euryhaline amphipod Gammarus lawrencianus at 20 and 30 Practical Salinity Units (PSU)
