“…The main sources of these pollutants in wastewater includes domestic, municipal, industrial, hospital, agricultural, and livestock as well as inadequate disposal of waste in the environment (Perez-Alvarez et al, 2018). A recent study has found phthalate esters in surface water, groundwater and drinking water, linked to phthalate ester-laden wastewater (Gani and Kazmi, 2016). At times the polluted water could be processed and recycled but the processing methods are usually not, perfectly e cient to purify wastewater to portable water.…”

Contaminants and pollutants impact on the availability of clean water for the human population is huge as clean water is increasingly scarce for human consumption on earth most especially in major cities of the world; As water is used they are heavily contaminated and hence there is the need to examine the persistent pollutants most especially phthalates and heavy metals in wastewater and outlet stream. This research examined the level of dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP), and heavy metals viz; Pb, Cr, Cd, As and Hg in the sewer and outlet stream in a part of Lagos, Nigeria. DMP ranged from 0.0070 ± 0.036 to 0.0278 ± 0.324, DEP ranged from 0.0367 ± 0.204 to 0.0526 ± 0.496, and DBP ranged from 0.0406 ± 0.241 to 0.1472 ± 1.667 µg/mL, lead ranged from 0.117 ± 0.024 to 0.157 ± 0.048, chromium ranged from nd (not detected) to 0.319 ± 0.245, cadmium ranged from 0.004 ± 0.002 to 0.063 ± 0.021, arsenic ranged from 0.002 ± 0.001 to 0.021 ± 0.006, and mercury ranged from nd to 0.007 ± 0.001 µg/mL. The concentration of lead in this study was higher than the WHO recommended value of 0.1 mg/L in surface water. This research established that phthalates and heavy metals were released into the wastewater from the immediate environment. We suggest that the sewer treatment of the wastewater be reviewed and improved to eliminate the contaminants in the wastewater.

“…Estrada-Arriaga et al (2016) observed comparatively higher concentration of PPCPs in dry season in the influent of two wastewater treatment plants with biological nutrient removal system integrated with coagulation, chemical precipitation, and neutral Fenton in Mexico. PPCPs like carbamazepine, dehydronifedipine, , and albuterol were found to be recalcitrant with very low removal efficiency.The neutral fenton process assured complete removal of most of the emerging contaminants Gani and Kazmi (2016). studied the seasonal variation in occurrence, fate and toxicity of phthalates including low molecular weight species like Diethylphthalate (DEP) and Dibutylphthalate (DBP) and high molecular weight species like Benzylbutyl phthalate (BBP) and Diethylhexyl phthalate (DEHP) in three different wastewater treatment plants involving SBR, conventional activated sludge process (ASP) and up flow anaerobic sludge blanket (UASB) with polishing pond.…”

This annual review covers the literature published in 2016 on topics related to the occurrence and fate of emerging environmental pollutants in wastewater. Due to the vast amount of literature published on this topic, we have discussed only a portion of the quality research publications, due to limitation of space. The abstract search was carried out using Web of Science, and the abstracts were selected based on their relevance. In few cases, fulltext articles were referred to better understand new findings. This review is divided into the following sections: Antibiotic resistant bacteria (ARBs) and antibiotic resistant genes (ARGs), disinfection by-products (DBPs), estrogens, nanomaterials, pathogens, perfluorinated chemicals (PFCs), pharmaceuticals and personal care products (PPCPs), and other pollutants.

In the recent years a group of contaminants, known collectively as emerging contaminants (ECs), have attracted considerable attention due to their widespread in the environment, and lack of knowledge on their impacts on ecosystem and human health. This review gives an overview on the sources, impacts, and conventional treatment technologies of ECs and an in‐depth review of the literature on the state‐of‐the‐art treatment technologies and their performance in the removal of ECs from water sources and drinking water. A careful statistical analysis of the number of publications on the different treatment technologies of ECs was performed to identify the hot spots in this research area. Conventional treatment technologies are not able to remove ECs sufficiently. The discharge of raw or partially treated wastewater is the main source of ECs in the environment. The research in recent years is focusing on using advanced treatment process (AOPs), followed by adsorption and membrane technologies. From a technical point of view, AOPs surpass other treatment technologies as they can completely eradicate ECs without the generation of side products. Developing efficient, green, and cost‐effective materials to be used as adsorbents, photocatalysts, membranes, or membrane fillers, is one of the main research trends nowadays. Combined AOPs based on exploiting solar light, ultrasound and electrochemistry are gaining growing interest and show high potential for the treatment of ECs.
