used water from the shallow well, there was some development of skin disease or there are foul smells," founder of Earth, Penchom Saetang said. "This is proof, that it is true, as the communities suspected, there are problems happening to their water sources." Depending on the age and type of the discarded item, the chemical composition of e-waste may vary. Most e-waste are composed of a mixture of metals like Cu, Al and Fe. They might be attached to, covered with or even mixed with various types of plastics and ceramics. E-waste has a horrible effect on the environment and it is important to dispose it with an R2 certifies recycling facility. Research In May 2020, a scientific study was conducted in China that investigated the occurrence and distribution of traditional and novel classes of contaminants, including chlorinated, brominated, and mixed halogenated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs, PBDD/Fs, PXDD/Fs), polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs) and polyhalogenated carbazoles (PHCZs) in soil from an e-waste disposal site in Hangzhou (which has been in operation since 2009 and has a treatment capacity of 19.6 Wt/a). While the study area has only one formal emission source, the broader industrial zone has a number of metal recovery and reprocessing plants as well as heavy traffic on adjacent motorways where normal and heavy-duty devices are used. The maximum concentrations of the target halogenated organic compounds HOCs were 0.1–1.5 km away from the main source and overall detected levels of HOCs were generally lower than those reported globally. The study proved what researchers have warned, i. e. on highways with heavy traffic, especially those serving diesel powered vehicles, exhaust emissions are larger sources of dioxins than stationary sources. When assessing the environmental and health impacts of chemical compounds, especially PBDD/Fs and PXDD/Fs, the compositional complexity of soil and long period weather conditions like rain and downwind have to be taken into account. Further investigations are necessary to build up a common understanding and methods for assessing e-waste impacts. Information security Discarded data processing equipment may still contain readable data that may be considered sensitive to the previous users of the device. A recycling plan for such equipment can support information security by ensuring proper steps are followed to erase the sensitive information. This may include such steps as re-formatting of storage media and overwriting with random data to make data unrecoverable, or even physical destruction of media by
