“…∑SCCP concentrations were detected at ND-5090 ng g −1 dw which indicated that CP production caused soil contamination of SCCPs. Only two studies were comparable with the obtained results (Xu et al 2016;Wang et al 2018b). The obtained results were also much higher than those reported by Bogdal et al (2017), Wang et al (2014) and Zeng et al (2011a).…”

“…Globally, the obtained results were generally higher than those in Japan, South Korea, India, UK and Norway (Borgen et al 2002;Barber et al 2005;Chaemfa et al 2014). Wang et al (2018b) also determined SCCP concentration in air samples from farmlands and villages surrounding the CP production plant in China. SCCP concentration in gas phase and particle phase ranged from 82 to 316 ng m −3 and 7 to 17 ng m −3 , respectively, and ∑SCCP concentrations in air samples were lower as the distance from the CP plant increased.…”

Chlorinated paraffins (CPs) have been applied as additives in a wide range of consumer products, including polyvinyl chloride (PVC) products, mining conveyor belts, paints, sealants, adhesives and as flame retardants. Consequently, CPs have been found in many matrices. Of all the CP groups, short-chain chlorinated paraffins (SCCPs) have raised an alarming concern globally due to their toxicity, persistence and long-range transportation in the environment. As a result, SCCPs were listed in the Stockholm Convention on Persistent Organic Pollutants (POPs) in May 2017. Additionally, a limit for the presence of SCCPs in other CP mixtures was set at 1% by weight. CPs can be released into the environment throughout their life cycle; therefore, it becomes crucial to assess their effects in different matrices. Although about 199 studies on SCCP concentration in different matrices have been published in other continents; however, there are scarce/or limited studies on SCCP concentration in Africa, particularly on consumer products, landfill leachates and sediment samples. So far, published studies on SCCP concentration in the continent include SCCPs in egg samples, e-waste recycling area and indoor dust in Ghana and South Africa, despite absence of any production of SCCPs in Africa. However, there still remains a huge research gap in the continent of Africa on SCCPs. Consequently, there is a need to develop robust SCCP inventories in Africa since the Stockholm Convention has already developed guidance document in this respect. This review, therefore, examines the state of knowledge pertaining to the levels and trends of these contaminants in Africa and further provides research gaps that need to be considered in order to better understand the global scale of the contaminant.

“…Standard stock solutions of MCCPs and SCCPs with different chlorine contents (C 14−17 42.0%, 52.0%, 57.0% and C 10−13 51.5%, 55.5%, 63.0%, 100 ng/μL in cyclohexane) and injection standard of ε-hexachlorocyclohexane (ε-HCH in cyclohexane, 10 ng/μL, 99.9%) were obtained from Dr. Ehrenstorfer GmbH (Augsburg, Germany). 13 C-1,5,5,6,6,10-Hexachlorodecane (100 ng/μL, >98%) was purchased from Cambridge Isotope Laboratories (Andover, USA).

“…1−3 Current research on CPs mainly focuses on SCCPs which show characteristics of persistence, long-range transport, bioaccumulation, and toxicity. 2,4−7 Studies have shown that SCCPs could be detected in various environmental and human samples, including air, 8,9 dust, 10,11 soil, 12,13 sluge, 14,15 biota, 16−18 human blood, 19 breast milk, and maternal and cord serum. 20,21 Since SCCPs have been listed in Annex A of the Stockholm Convention in 2017, 22 the production and usage of MCCPs as replacement chemicals is increasing.…”

For the most complex artificial chlorinated environmental contaminants, much less is known for medium-chain CPs than short-chain CPs. In this research, the spatial distributions of MCCPs and SCCPs in farmland soil and maize leaves near a CP production facility were found marginally influenced by seasonal winds. The levels of ∑MCCPs and ∑SCCPs were in the ranges of <1.51−188 and 5.41−381 ng/g dw for soils; and 77.6−52930 and 119−61999 ng/g dw for maize leaf, respectively. Bioaccumulation and tissue distributions of the CPs within maize plants were specifically analyzed. Most of the CPs were contained in the tissues directly exposed to airborne CPs. Though the estimated risk of CPs to humans through ingestion of kernels appears to be minimal, the edible safety of MCCPs in maize plants for cattle was nearly in the designated range of adverse effects. To our knowledge, this is the first report on bioaccumulation of CPs in mature maize plants, especially in the parts eaten by humans and domestic animals. It provides a baseline reference to the edible risks of CPs in agricultural food plants and alerts us to the problematic environmental behavior of MCCPs, a probable future replacement for SCCPs commercially.

BACKGROUND: This article focuses on the health risk assessment associated with air pollution for the population of the Temir district in the Aktobe region. The risk assessment of the effects of air pollution on public health revealed a tendency to deterioration in the health indicators of the children’s population. AIM: The research object was the population of the Temir district living near the oil and gas field Zhanazhol. METHODS: The work was carried out according to the risk assessment methodology described in the manual R 2.1.10-1920-04. The maximum non-carcinogenic risk due to exposure to chemicals in the air basin of residential areas was established for children from 0 to 6 years of age in the Temir district. RESULTS: A high risk of respiratory, blood, and cardiovascular diseases was observed. Sulfur dioxide, hydrogen sulfide, nitrogen, and carbon oxides contained in atmospheric air contribute to the risk of developing these diseases. The levels of carcinogenic risk to public health in the Temir district show that the maximum individual risk of oncological diseases is observed in the group of children. The risk of malignant neoplasms in adolescents is 1.2 times lower, in the male population – 1.4 times lower, on average, and in the female population – 1.3 times lower than in children. Public health risk analysis aims to select the best ways in a particular situation to eliminate or reduce risk associated with air pollution for the population. CONCLUSION: The methodology of a comprehensive health risk analysis is a promising and developing approach in the system of monitoring the quality of the human environment and assessing environmental hazards.
