The Correlation Between Green Open Space with Carcinogen Toxicity Score of Benzene in Shoes Home Industry Surabaya

Benzene is a carcinogenic substance that can be found as chemical compounds in shoes-making industries that use glue as a raw material. The objectives of this research were to identify the presence of Green Open Space (GOS), GOS requirement, benzene concentration in work environment, carcinogen toxicity score of benzene, and to analyze the correlation of GOS with carcinogen toxicity score of benzene. This research was an observational research, cross-sectional analysis with the sample of 10 people determined by purposive sampling technique. The data analysis was using cross tabulation and statistic prevalence risk (PR) method to find out the correlation of the presence of GOS with carcinogen toxicity score of benzene. The results showed that most respondents (70%) did not have green open space. Analysis of Green Open Space requirement calculation for 10 respondents in 10 work locations got the value of private GOS requirement of 104.8 m2. There was a 10% sampling point with a benzene concentration (2.91 mg/m3) that exceeds the threshold value (1.6 mg/m3). The carcinogen toxicity score of benzene differed in each workplace where the highest was in the 9th location with the value of 0.160. There was a correlation between the presence of Green Open Space and carcinogen toxicity score of benzene (PR>1) in which workplaces without a GOS at risk of 1.555 times had a higher carcinogenic toxicity score compared to sites with Green Open Space. Suggestion as an alternative of GOS presence at the workplace was by planting ornamental plants in hanging pots such as Spider plant, Boston fern, Peace lily, Dutch betel, and Golden pothos that was effective in reducing benzene contaminants. In addition, it was suggested to consume foods with CYP2E1 enzymes contained in beef liver and salmon to decrease benzene levels in the body
