The air pollution in the garbage dump gave the bad effect for the environmental health , NH3, H2S and the other polluted gases were the causes of air pollution that could give the bad effect for health, especially respiratory disorders. The garbage dump of bukit pinang was located in samarinda and still used open dumping method that could cause environmental pollution. Research design used cross sectional approach. The sample of NH3 and H2S was taken at 3 points and there were 34 respondents that were chosen using purposive sampling. Data collection included in the measurement of NH3 and H2S, interview, and observation of respiratory disorders. Data analysis used t-independent test with 95% of confidence level.Result of the study showed that the concentration of NH3 and H2S at garbage dump of Bukit Pinang at sample points I, II, and III was still under quality standard. Result of T - Independent showed that there was relationship among concentration of NH3 (ρ-value= 0,005), concentration H2S (ρ-value=0,042), exposure period of NH3 and H2S (ρ-value=0,000), and Risk Quotient NH3 (ρ-value=0,000), H2S (ρ-value=0,000) with the respiratory disorders of the people around the garbage dump of  bukit pinang. Result of Mann-Whitney test showed that there was no relationship between exposure frequency of NH3 and H2S (ρ-value=0,284) with the respiratory disorders of the people around the garbage dump of bukit pinang

Air pollution is estimated to cause more than 7000 deaths annually in Sweden alone. To reduce the impact of air pollution and to plan and build sustainable cities, it is vital that research is translated into efficient decisions and practice. However, how do civil servants in a municipality access research results? How do they normally find relevant information, and what obstacles are there to accessing and applying research results? As part of the collaborative and transdisciplinary research project Air Pollution Research in Local Environmental Planning (ARIEL), these questions were explored through interviews and seminars with civil servants within the Malmö Municipality Environmental Office. We found that the civil servants generally have proficiency in processing research results, but often do not use such results as part of their everyday decision making and practices. Instead, the data and measurements used are mostly produced case-by-case within the municipal sector itself. Information about best practices is also collected via a number of knowledge access practices, involving the Internet or social networks within other municipalities. Lack of time, paywalls, and the insufficient applicability of research hinder the dissemination of up-to-date results. This slows down the process whereby research, funded by tax-money, can be put to best practice in the effort to create healthy and sustainable cities.
