The inclusive ideals of George Sánchez have helped shape a new generation of academics who have promoted connections with nonacademic organizations. This article discusses how Sánchez has continued these efforts through his pivotal contributions to an award-winning documentary focusing on the multiethnic, working-class community of Boyle Heights: Betsy Kalin’s film East LA Interchange (2015). East LA Interchange’s greatest contribution to the generative scholarship Sánchez emphasizes is its critical analysis of modern urban problems, utilizing history as a tool for social change. The story of Boyle Heights is not just a history of a single working-class community with a diverse culture. It is also a tale of a neighborhood trying to solve real world problems such as gentrification, unaffordable housing, community displacement, and urban pollution. The film portrays these difficulties in the present while showing that they originated decades ago. Sánchez and East LA Interchange are at their best when they provide the historical contexts of contemporary problems, emphasizing that history is not only the study of the past. Rather, history is the unending dialogue between the past, present, and future, and any significant discourse on today’s urban ills must be rooted in the past. For students and others interested in the diverse communities common in many US metropolitan regions, East LA Interchange has much to offer regarding the issues of immigration, redlining, deed restrictions, political activism, freeway construction, living with racially and ethnically diverse community members, and the nationwide problem of gentrification. These themes, especially gentrification, are the primary focus of this article.

The aim of this paper was the application of statistical analysis including principal component analysis to evaluate heavy metal pollution obtained by moss technique in the air of Ha Noi and its surrounding areas and to evaluate potential pollution sources. The concentrations of 33 heavy metal elements in 27 samples of Barbula Indica moss in the investigated region collected in December of 2016 in the investigated area have been examined using multivariate statistical analysis. Five factors explaining 80% of the total variance were identified and their potential sources have been discussed.

This study attempted to analyze the distribution and contamination status of heavy metals (Cu, Fe and Zn) along western coast of Bali Strait in Banyuwangi, East Java. Bali Strait is one of the many straits in Indonesia with high fisheries activities that could potentially contributed to high heavy metal pollution. There were five sampling areas from the north to south: Pantai Watu Dodol, Pantai Kalipuro, Ketapang Port, Pantai Boom and Muncar as the fish landing area. Heavy metal pollution in these locations comes from many different activities such as tourism, fish capture and fish industry and also domestic activities. Contamination factor (CF), geo-accumulation index (Igeo) and enrichment factor (EF) of each heavy metal were calculated to obtain contamination status of the research area. The concentrations of Fe were observed the highest (1.5-129.9 mg/kg) followed by Zn (13.2-23.5 mg/kg) and Cu (2.2-7.8 mg/kg). The distribution of Cu, Fe and Zn showed variability among the sampling locations in which high concentrations of Cu and Zn were higher in Ketapang Port, whereas high concentration of Fe was high in almost all sampling locations. According to the pollution index, contamination factors of Cu, Fe and Zn were low (CF < 1 and Igeo < 1). However, high index of EF (> 50) showed high influence of the anthropogenic activities to the contribution of the metals to the environment. This could also because of the high background value used in the calculation of the index due to the difficulties in finding background value from the sampling areas.Keywords: heavy metals, pollution index, contamination factor, geo-accumulation index, Bali Strait
