“…As Table 2 shows, in some cases, turbidity and COD were higher than the permissible limits and DO was much lower than the minimum permissible limit in the EQA. The TSS levels for [41] exceeded the USEPA freshwater limit, which is not surprising. However, pH was in the standard range for all studies.…”

“…Generally, carwash cleaning products contain high amounts of detergents and alkaline liquids, but in recent years, carwash centers have increased the amounts and types of chemicals and surfactant compounds used in their detergents. This has resulted in significantly greater amounts of pollution being generated from vehicle cleaning [41]. As Table 2 shows, in some cases, turbidity and COD were higher than the permissible limits and DO was much lower than the minimum permissible limit in the EQA.…”

Exploring the Potential in LID Technologies for Remediating Heavy Metals in Carwash Wastewater

Carwash wastewater (CWW) can be a significant source of environmental pollution due to the diversity and high concentrations of contaminants it contains. This toxic wastewater can contain several different heavy metals that if left untreated, can enter surface and sub-surface waters. Innovative, nature-based solutions such as low-impact development (LID) technologies may provide an eco-friendly CWW treatment process that is both effective and affordable. This research reviews the available literature to provide definitive values of flowrate and contaminant concentrations found in CWW around the globe. Dividing LID technologies into two groups, vegetated and unvegetated systems, the authors explored the literature for the general performance of these technologies to sustainably treat heavy metals in CWW. Depending on the car wash’s size and intended purpose, whether cleaning vehicles in agriculture-based rural communities, mining, or in high-density urban environments, volumetric flowrates requiring treatment found in six different countries ranged from 35–400 L/car. CWW also contains a wide range of contaminants at various levels, including COD, turbidity, TDS and TSS, surfactants, oils and greases, and heavy metals such as lead, cadmium, zinc, copper, chromium, and iron. Heavy metal removal by both vegetated and unvegetated LIDs shows mixed results in the literature, but given the different processes involved in both types, the authors propose a system that combines these types in order to provide all the necessary removal processes, including mechanical filtration, adsorption, sedimentation, chemical and biological treatment processes.

Global Decline of Insects

There are lot of reasons and causes of insect decline. The main causes of insect decline is attributed to habitat destruction, land use changes, deforestation, intensive agriculture, urbanization, pollution, climate change, introduction of invasive insect species, application of pesticides, mass trapping of insects using pheromones and light traps, pathological problems on various insects, and introduction of exotic honey bees in new areas that compete with the native bees for resource portioning and other management techniques for pest management, and even not leaving any pest residue for predators and parasitoids for their survival. The use of chemical insecticides against target or non-target organisms is major cause for insect decline. The diseases and decline of the important pollinators is still a mistry for colony collapse disorder. To overcome the cause of insect decline, various conservation techniques to be adopted and augmentation of artificial nesting and feeding structures, use of green pesticides, maintaining the proper pest defender ratio (P:D), policies and reaching to political audience at global level and other factors already discussed in the chapter may be helpful for mitigating the insect decline and especially for the pollinators, a key insect for life.

“…Lessen soap runoff from washing vehicles and building exteriors, and reduce use of driveway sealants and de-icing salts. Soaps used to wash cars, motorbikes, or the exteriors of buildings often produce significant quantities of pollutants including ammonia, heavy metals, nitrogen, petroleum hydrocarbons, phosphorus, and surfactants that can drain directly into local water systems (34). Natural waterways contain a diversity of aquatic insects, including some of the most threatened animals on Earth (5).…”
