Bisphenol A

Bisphenol A (BPA) is used in the production of polycarbonate plastics and epoxy resins. BPA is produced in large amount (U.S. Environmental Protection Agency (EPA), 2014). Moreover, daily items are mainly contains BPA (Rochester, 2013).
Most people are exposed to BPA through their diet and this is due to present of BPA in food and beverages (National Institute of Environmental Health Sciences, 2010). This make human easily expose to BPA. In addition, inhalation and transdermal can lead to exposure to BPA (Konieczna, Rutkowska & Racho?, 2015). Moreover, the BPA source of contamination can happen through wastewater, air, dust and soil (Valentino et al., 2016).
BPA can be leach into our food and water supplies as it is function to coat the lining inside of food and drinks cans. BPA can bring many health problems to human. BPA is an endocrine disruptor and it can influence secretion, transportation and elimination of natural hormones. It can lead to reproductive disorders which may lead to infertility (Nordqvist, 2017).

There are several common methods to extract BPA from environmental water samples. Liquid-liquid extraction (LLE) and solid-phase extraction are regularly been used to extract BPA. Both of these methods involved very complicated procedure, time-consuming and used of large quantities of organic solvents. (Sarafraz-Yazdi & Amiri, 2010).
There are some new methods introduced to compensate for the less-ideal behaviour of LLE and Solid phase extraction (SPE). Dispersive liquid-liquid microextraction (DLLME) and solid-phase microextraction (SPME) are used to meet the green chemistry requirements. These methods have some advantages include fast, inexpensive, easy to operate and consumes low volume of organic solvents (Rezaee, Yamini & Faraji, 2010).
