This review also presents logistical considerations of implementation of the technologies, including waste management which can be an extreme impediment to rapid remediation if generated quantities of hazardous waste exceed local handling capacity. While the underlying chemical and physical mechanisms that contribute to transport differ among contaminants, the studies reviewed here might also be applicable to non-radioactive contaminants, because the...

these tests were then repeated using the industrial paint currently used in the processes. VOC saturation is achieved for exposure times between 5 and 15 min in the aqueous effluent. The system of absorption and ozonation is effective for the elimination of the released VOCs, achieving a 94% reduction in the COD of the wastewater. Finally, it was observed that...

Mean ΣPAH C free determined by the biosensor for the four sediments (3.1 to 55 μg/L) were within a factor of 1.1 (on average) compared to values determined by the passive samplers (2.0 to 52 μg/L).. The biosensor was also useful in identifying sediments that are likely to be non-toxic to benthic invertebrates. In two of the four sediments, biosensor...

Organic substrata, namely wood - and coconut fibre, demonstrated higher sorption affinity compared with the inorganic substrata mineral wool and pumice, notably regardless of the micropollutants’ Log K ow . Constructed wetlands (CWs) are commonly applied secondary or ter- tiary wastewater treatment systems ( Zhang et al., 2017a. Numerous studies reported the adverse effects of micropollutants on human and environmental...

The removal rate of Phe, Pyr and BaP using the co-immobilized fungal-bacterial consortium within 60 d was and respectively, which was obviously higher than that of free fungal-bacterial consortium in the same time. Ten percent (w/w) was the optimal amount of inoculum for PAH degradation in the co-immobilized fungal-bacterial consortium. The detection rate has increased from less than 20% to...

A 10-fold increase in BPA-BDPP and PBDPP concentration was associated with a 4.1 and 2.6 point increase on the internalizing problems scale (respectively p = 0.004 and p = 0.042). Exposure to industrial chemicals is nowadays recognized as con- tributors to the rise of neurodevelopmental disorders, including atten- tion deficit and hyperactivity disorder (ADHD) and autism, and subclinical brain dysfunction,...

(http://creativecommons.org/licenses/by-nc-nd/4.0/).. Schistosomiasis and soil-transmitted helminth (STH) infections are the most widespread parasitic tropical diseases, especially in low income settings with limited access to clean water and sanitary facilities (Boko et al., 2016). The global burden due to schistosomiasis and soil trans- mitted helminthiasis was estimated at about 7.09 million Disability-Adjusted Life Years (DALYs) (Herricks et al., 2017). Schistosoma haematobium, causing...

Azole pesticides Biochar Fe/Mg-MIL-88B Magnetic adsorbent. The adsorption performance of MBC@Fe/Mg-MIL-88B composites was systematically investigated and the maximum adsorption capacity towards epoxiconazole and flusilazole were 86.11 mg g − 1 and 89.87 mg g − 1 , respectively. The MBC@Fe/Mg-MIL-88B could adapt to a relatively wide range of pH (2-11). The adsorption of azole fungicides onto MBC@Fe/Mg-MIL-88B was a single-layer...
