Removal of pharmaceuticals from wastewater by fungal treatment and reduction of hazard quotients

Science of The Total Environment, 2016
The elimination of 81 pharmaceuticals (PhACs) by means of a biological treatment based on the fungus Trametes versicolor was evaluated in this work. PhAC removal studied in different types of wastewaters (urban, reverse osmosis concentrate, hospital, and veterinary hospital wastewaters) were reviewed and compared with conventional activated sludge (CAS)

Target hazard quotient evaluation of cadmium and lead in fish from Caspian Sea

Toxicology and Industrial Health, 2013
Heavy metals are being increasingly released into the natural waters from geological and anthropogenic sources. The distributions of several heavy metals such as cadmium (Cd) and lead (Pb) were investigated in muscle and liver of three different fish species seasonally collected from Caspian Sea (autumn 2011–summer 2012).

Estimated Daily Intake and Hazard Quotients and Indices of Phthtalate Diesters for Young Danish Men

Environmental Science & Technology, 2013
Because of wide exposure to phthalates, we investigated whether simultaneous exposure to several phthalates reached levels that might cause adverse antiandrogenic effects. Thirty three healthy young Danish men each delivered three 24-h urine samples during a three months period.

Compound Heavy Metal Contaminated Site Risk Assessment Based on Hazard Quotients

Advanced Materials Research, 2011
On the basis of investigation of specific heavy metals contaminated site, use compound heavy metal hazard quotients to do a assessment for potential health risk. The primarily detected excessive heavy metals are Zn, Gr, Cu and Hg. Results indicate that: in the surface (0~30 cm) and subsurface (30~70 cm), the compound heavy metal hazard quotients of ...

Fluoride content and hazard quotient for beverages marketed in iran

2021
Beverages are one of the main sources of fluoride (F) entry to the body, especially in some countries located in the tropical regions. The aim of this study was to determine, for various beverages available in markets in Iran, the F concentration, the estimated daily intake, and the hazard quotient value (HQ), a measure of non-carcinogenic risk.

Disappearance and hazard quotient of chlorpyrifos-methyl, fipronil, and imidacloprid insecticides from dates

Journal of Consumer Protection and Food Safety, 2017
Control strategies of red palm weevil (RPW) mainly depend on the use of insecticides. However, the residue of insecticides in dates might cause poisoning risk to the consumers. Therefore, the present study aimed to measure the disappearance rates of the extensively applied insecticides on date palm trees. Residues of chlorpyrifos-methyl (CPM), fipronil

Mercury, cadmium and lead contamination in seafood: A comparative study to evaluate the usefulness of Target Hazard Quotients

Food and Chemical Toxicology, 2009
The aim of this paper is to explore the applicability of Target Hazard Quotient (THQ) estimations to inform on seafood hazards through metal contamination. The food recall data set was collated by the Laboratory of the Government Chemist (LGC, UK) over the period from January to November 2007.

Lead Levels in Breast Milk, Blood Plasma and Intelligence Quotient: A Health Hazard for Women and Infants

Bulletin of Environmental Contamination and Toxicology, 2011
Lead levels in human breast milk and blood plasma or serum were analyzed and qualitatively their intelligence quotient (I.Q.) studied. Samples at different stages of lactation, from 5 days to 51 weeks post partum, were collected from 25 healthy breast-feeding mothers in Ranipet Industrial area of Vellore district of Tamil Nadu and from 25 lactating ...

Estimation of dietary intake and target hazard quotients for metals by consumption of wines from the Canary Islands

Food and Chemical Toxicology, 2017
This paper describes the impact of mineral content on wines and assesses the potential health risk from consuming these wines from Canary Islands. The metal content (B, Ca, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Zn) of red wines belonging to different regions in the Canary Islands was determined by ICP-OES.

Application of the Hazard Quotient Method in Remedial Decisions: A Comparison of Human and Ecological Risk Assessments

Human and Ecological Risk Assessment: An International Journal, 2003
This paper evaluates the relative roles of the human health hazard index (HI) and the ecological risk assessment hazard quotient (HQ) in remedial decision-making. Through an analysis of HI outcomes drawn from Superfund Records of Decision, the reduced importance of the HI statistic in human health risk assessments is demonstrated, and the high ...
