Pharmaceuticals and personal care products (PPCPs) have been widely detected in aquatic environment in recent years; as emerging micro-pollutants, their influence on human health and ecological environment safety are of increasing concern. Membrane filtration is considered as the suitable separation method for PPCPs removal due to different removal mechanisms. This paper reviews the removal efficiency and removal mechanisms for PPCPs by NF/RO membranes.

Human Health Impacts

Plastic pollution is one of the prime and alarming issues in developing countries that has vast environmental and human health impacts which need to be addressed as a priority. Unfortunately, limited work has been done on the topic, especially on air and water pollution due to plastics in Pakistan. Informal solid waste management is being done by municipalities, which is not adequate, and the problem will increase with the upsurge in population and industrialization. There is a need to address the knowledge gap and improvements in the existing conditions to manage the issue of plastic pollution separately. In this chapter, causes; impacts of plastic pollution both on human and environmental health, plastic industries, and legislative context; and best practices to manage plastic pollution along with some important recommendations are discussed. It is expected the data presented may help the managers, environmental scientists, and policymakers to manage the problem of plastic pollution.

River Water Pollution

This study was conducted to evaluate the Kapotaksha River water pollution status and its impacts on Human health and Environment. This study conducted a case study on four selected areas (Barakpur, Srirampur, Prbazar, and Gouranandapur) on the Kapotaksha river bank at Jhikargas Upazila. This river water pollution occurs by some natural process such as flood, storm, and natural biodegraded. But human activities are major reasons for the river water pollution. Industrialization, urbanization, domestic waste, sewage system, agrochemicals, etc are major causes for river water pollution. This more polluted water has an impact on human health and environment. This study was conducted to find out the polluted water due to various types of diseases such as scabies, asthma, dysentery and respiratory disease. Most of the people (49%) are affected by Scabies, 4% are affected by diarrhea, 5% are affected by dysentery, 25% of people are suffering from respiratory diseases and 4% are suffering from asthma and the polluted water pollutes soil by using the water in agriculture purpose answered by 20% respondents which is 100% of farmer respondents. If someone does not use this water can not affect soil answered by 80% of respondents. This river water becomes more polluted and harmful for human health and environment because this water hampered by the local colony, local trader, lack of proper management of sewage system, miss-use on the riverbank area for the dumping various solid waste on the river bank, chemical fertilizers, industries etc. At present now we cannot fulfill control this continuous river water pollution but we can minimize this problem and it would be positive for human health, others living organisms and Environment.

Abstract Rhodamine B (RhB), widely used as an industrial dye, is a toxic organic that is hazardous to human health and can cause water pollution. In this study, the removal rate of RhB was investigated by the following methods: hydrodynamic cavitation (HC) operated individually, and HC combined with oxidants H2O2 or ClO2. The effect of different operating parameters including pressure (2–6 bar) and initial pH (2–8) on the extent of degradation was investigated using an orifice plate as the cavitation device to achieve maximum removal of RhB. Under the parameters of HC, the effect of different loadings was investigated: H2O2 (n(RhB):n(H2O2) was varied from 1:17.60 to 1:211.28) and ClO2 (n(RhB):n(ClO2) was varied from 1:8.87 to 1:177.53). A combination of cavitation and H2O2 or ClO2 resulted in degradations of 80.6% and 95.3%. The results indicated that the combination of HC and oxidants was better than the individual HC process for the degradation of RhB. When combining HC with H2O2 or ClO2, the synergistic coefficients of 62.54 and 74.79 were obtained. The combination of HC and ClO2 was proven to be more effective for the removal of RhB compared to HC alone and the hybrid process of HC and H2O2.
