“…3 Inadequate management of wastes can result in water and soil pollution, greenhouse gas emissions, and negative impacts on human quality of life. [4][5][6] Apart from health and environmental hazards, other problems of mass production of solid wastes are waste storage, collection, and disposal management. 7 For any municipal waste management plan to be successful, it is important to consider separation of the wastes at source where community participation plays a key role.…”

Introduction: In the management of recycling waste, separation of the wastes from source is crucially important. A successful source separation plan requires good participation of the community. Objective: The purpose of this study was to evaluate the effect of an educational intervention based on the Integrated Behavior Model (IBM) on the behavior change of housewives in Sanandaj City, west of Iran, towards the waste separation at source. Methods: This is a quasi-experimental and community trail study. The population study was the households living in Sanandaj. The total number of 144 households were selected and divided into two groups (72 each). For each selected household, only the housewife was interviewed. To evaluate the behavior change towards the dry and wet waste separation, a training program based on the IBM was conducted for one group (training or intervention group) and the second group served as the control and received no training. The length of the intervention was two months with eight sessions. After a month, participants were asked to fill in a validated questionnaire based on the IBM, before and at the end of study. Data were analyzed using Wilcoxon and McNemar tests. Results: In the intervention group at the baseline, the mean ± standard deviation of the attitude, subjective norms, perceived behavior control, and self-efficacy score were 34. 03 ± 5.12, 15.91 ± 4.58, 18.93 ± 4.01 and 31.54 ± 6.79 respectively. At the end of study, the score of components increased to 36 ± 4.28, 18.9 ± 4.56, 21.76 ± 2.65 and 34.72 ± 4.66 respectively. The increase in the components was statistically significant (p < 0.05). Conclusions: The intervention based on IBM could be an effective method to improve the behavior of separation the dry and wet waste.

“…The significant difference of metal elements between plastic material was p < 0.05, according to Tukey's HSD post hoc test and Kruskal-Wallis test. In the Persian Gulf, higher concentrations of metals (Mn, Al, Fe, Cd, Cr, Ni, Pb, and Cu) in the sediments than those in plastics have been reported by Dobaradaran et al [39].…”

Background: Pollution by marine plastic debris becomes an increasing global concern. Characteristics of petroleumbased plastics pollution and its absorbed metals in Marina Beach, Chennai, in India are not reported yet. In this study, we first characterized the petroleum-based plastic debris and quantified the concentration of arsenic (As), chromium (Cr), copper (Cu), and lead (Pb) in plastics from the Marina Beach. Results: A total of 2275 samples of the sediments were collected from three different locations across the Marina Beach. Our results showed that plastics debris mainly were three shapes as fiber, sphere, and fragment. The plastic fragments were mechanically eroded and chemically weathered observed by the scanning electron microscope (SEM). Five types of polymers were identified, including low-density polyethylene (LDPE), polyethylene terephthalate (PET), polypropylene (PP), polyamide (PA), and polycarbonate (PC). Their absorbed trace metals, such as Cr, As, Pb, and Cu, were determined by the inductively coupled plasma mass spectrometry (ICP-MS). The level of As was high in most plastics. However, the highest levels of Pb, Cu, and Cr were in the PA, PP, and PA, respectively, implying the adsorption preference of plastics from different sources. Conclusion: Taken together, this study first characterized petroleum-based plastics and their absorbed trace metals in the sediments of the Marina Beach, indicating that petroleum-based plastics acted as the vectors for the transportation of metal elements in the marine biome.

“…Though polymers were considered to be inert towards metals in the past [97], great attention has recently been paid to better understanding the interaction between heavy metals and microplastics [98][99][100][101][102][103][104][105][106][107][108].…”

The distribution and abundance of microplastics into the world are so extensive that many scientists use them as key indicators of the recent and contemporary period defining a new historical epoch: The Plasticene. However, the implications of microplastics are not yet thoroughly understood. There is considerable complexity involved to understand their impact due to different physical–chemical properties that make microplastics multifaceted stressors. If, on the one hand, microplastics carry toxic chemicals in the ecosystems, thus serving as vectors of transport, they are themselves, on the other hand, a cocktail of hazardous chemicals that are added voluntarily during their production as additives to increase polymer properties and prolong their life. To date, there is a considerable lack of knowledge on the major additives of concern that are used in the plastic industry, on their fate once microplastics dispose into the environment, and on their consequent effects on human health when associated with micro and nanoplastics. The present study emphasizes the most toxic and dangerous chemical substances that are contained in all plastic products to describe the effects and implications of these hazardous chemicals on human health, providing a detailed overview of studies that have investigated their abundance on microplastics. In the present work, we conducted a capillary review of the literature on micro and nanoplastic exposure pathways and their potential risk to human health to summarize current knowledge with the intention of better focus future research in this area and fill knowledge gaps.
