Effluent Discharge

In urban areas, wastewater treatment plants (WWTPs) play a major role in the water quality of rivers. The removal efficiency of emerging contaminants by WWTPs is strongly correlated with the type of treatment and the hydraulic retention time (HRT) of the process, which can vary according to the volumetric influent flow of wastewater and occasional peak flows. This paper aims, for the first time, to assess the daily variation of lipid regulators and personal care products in an urban river impacted by domestic effluents. Samples were collected upstream and downstream of a WWTP. The concentrations downstream of the effluent discharge were higher than upstream, but they varied significantly during the day. Concentration peaks upstream of the WWTP were detected at 07:00, 15:00 and 21:00, while downstream of the effluent discharge, concentration peaks occurred between 13:00 and 19:00 and between 21:00 and 23:00. The highest downstream concentrations of triclosan and methylparaben (420 ng L−1 and 460 ng L−1) were 6.8 and 5.4 times higher than the lowest concentrations detected, respectively. These results show that in WWTP-impacted rivers, the time of the sampling has a great influence on the final results and conclusions of a monitoring study.

Abstract Solid-phase microextraction (SPME) is a sample preparation technique with many applications that is being continuously developed. In this technique, the type of fiber coating plays a crucial role for extraction efficiency. Currently available commercial coatings have certain drawbacks that have been overcome by the development of new coatings based on novel materials; these have improved the efficiency of extraction, selectivity and stability of commercial coatings. Pharmaceutical and personal care products (PPCPs) are one of the most important groups of emerging contaminants; however, some studies suggest that these compounds can cause adverse health effects. No official monitoring protocols for these compounds are currently available, so the establishment of analytical methods that allow their determination in environmental samples is required. The complexity of environmental samples together with the low concentration levels of these compounds makes necessary the use of sample preparation techniques capable of removing interferences, as well as preconcentrated analytes, and SPME is a very promising alternative to achieve this. This review describes the recent developments in SPME with classical and novel coatings and its applications for PPCP determination in environmental samples.

With the advent of better detection, more micro-contaminants are being found in water. Many of these micro-contaminants come from medical therapies and personal care products. These chemicals are comprised of a wide-range of substances including pharmaceuticals, dietary supplements, veterinary drugs, fragrances, hair care products, body lotions, oral care, and cosmetics. Many of these products enhance our quality of life and in some cases, provide life-saving therapies. But, they come with an environmental cost. Scientific research has found sub-therapeutic levels of many of these chemicals in our waterways and in our finished drinking water, causing concern about the potential environmental and public health impacts associated with very low, chronic exposure. As tailored therapies and personal care products are developed, it is crucial to consider how to control emerging contaminants from medical therapies and personal care products. Specific actions and policies can be implemented now by adopting upstream approaches to prevent waste and decrease environmental exposures.

Environmental Relevance

The presence of personal care products in the environment is recent and relatively few researches work with the quantification of this class of emerging contaminants in Brazil. However, a wide variety of these products is continuously released into the aquatic environment. The growing interest in these substances occurs mainly because they exhibit biological activity in very low concentrations, which gives great environmental relevance. The difficulty of detecting and quantifying such contaminants in the environment encourages the development and validation of appropriate analytical methods for this purpose. Therefore, the present study aims to validate a methodology and verify its efficiency in the determination of six personal care products, among them parabens and triclosan. The samples were submitted to the solid phase extraction process and were later analyzed by gas chromatography coupled with mass spectrometry for the determination of personal care products. The validation of the methodology used was based on the standards established by the National Health Surveillance Agency. The extraction and quantification method were efficient for the determination of these analytes in water samples.

Abstract The presence of emerging contaminants such as pharmaceutical and personal care products in many aqueous matrices have been reported. One of such matrix is streams of wastewater, including wastewater treatment plants inflows and outflows and wastewater flow by-passing wastewater treatment plants. Their persistence arises from their resistant to breakdown, hence they may remain in the environment over long time, with a potential to cause adverse effects including endocrine disruption, gene toxicity, the imposition of sex organs, antibiotic resistance and many others in some aquatic organisms exposed to arrays of residues of pharmaceutical and personal care products. Among the treatment techniques, advanced oxidation processes have been reported to be a better technique through which these PPCPs can be degraded in the WWTPs. Heterogeneous photocatalysis using various photocatalyst immobilized on solid support such as activated carbon, graphene and carbon nanotubes in AOPs have been shown to be a viable and efficient method of PPCPs degradation. This is because, the performance of most WWTPs is limited since they were not designed to degrade toxic and recalcitrant PPCPs. This review highlight the occurrence, concentration of PPCPs in wastewater and the removal efficiency of heterogeneous photocatalysis of TiO2 immobilized on solid supports.

A group of potential emerging contaminants in two Irish drinking water supplies were investigated. The aim was to investigate the presence of emerging contaminants which are not currently routinely monitored or regulated as part of the European Communities Drinking Water Regulations SI 278 of 2007 but are known or anticipated to occur in drinking water supplies. A monthly sampling and analysis programme was carried out to examine the presence of seven groups of potential emerging contaminants in two Irish drinking water supplies. The seven groups selected were: herbicides, molluscides, endocrine disrupters, perfluorinated chemicals, disinfection by-products, personal care products, and heavy metals. The investigation showed that the majority of the seven selected groups of contaminants were not detected at either drinking water site. Results from the first site (water treatment plant (WTP) 1) showed elevated levels of musk xylenes, a member of the personal care products suite of tests. The specific compound detected was galaxolide, a polycyclic musk found in perfumes, soaps, cosmetics and detergents. Results from the second site (WTP 2) showed elevated levels of oestrone, a member of endocrine disrupter steroid suite of tests. Oestrone is one of three types of oestrogen made by the body and is produced by the ovaries as well as by adipose tissue and the adrenal glands. Results from both sites showed that of the seven groups of contaminants chosen for examination most were not detected. The musk xylene compound galaxolide was detected on one occasion at a level just above the guideline limit and oestrone a component of the endocrine disrupting chemicals steroid suite of tests was found on two occasions throughout the study.
