Two research questions and two hypotheses guided the study. A descriptive survey research designed was adopted for the study. A total population of 155 respondents comprises of 97 highly experienced registered air conditioning service technicians and 58 moderately experienced registered air conditioning service technicians in Niger State. The respondents were selected according to the year of service, which was 1-14 years for moderately experienced and 15 above for highly experienced service technicians. Due to manageable sizes of the respondents, the entire population was used i.e no sampling techniques was utilized for the study. A structured questionnaire title “Automotive Air Conditioning System Maintenance Practices Questionnaire” was faced validated by three experts (one lecturer from Department of Industrial and Technology Education, Federal University of Technology Minna, one expert from Ministry of Environment Niger State and one expert from Ministry of Health Niger State). The questionnaire was pilot tested using 30 automotive air conditioning service technicians from Abuja. The data collected were analyzed using Cronbach Alpha Statistics and its yielded to 0.71 reliability coefficient. Mean and standard deviation were used to analyze the research questions and hypotheses were tested at 0.05 level of significance using z-test statistics. The numerical values obtained from the responses of the respondents were tabulated and analyzed using statistical package for social science (SPSS) version 23. The findings among other revealed that  inhalation of concentration refrigerant vapour is dangerous and can be fatal, exposure to level of fluorocarbons above recommended exposure levels can results in loss of concentration and drowsiness, inhaling refrigerants adds to the effect of chronic illness. It is recommended amongst other that hazardous automotive air conditioning waste generated by automotive service technicians’ shops should always be removed by licensed personnel under the supervision of environmental agencies. Manufacturer instructions on refrigerants should be followed by technicians.","PeriodicalId":32450,"journal":{"name":"IJEMS Indonesian Journal of Environmental Management and Sustainability","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81794761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study of Ichthyofauna was conducted at nine areas of Enipeas river basin in central Macedonia region of Greece. At the sampling stations, the electrofishing method was applied. The physicochemical parameters at the sampling site were measured with a multiparametric HANNA water quality meter, while water samples were collected and transferred to laboratories of the Biology Department of the Aristotle University of Thessaloniki for analysis of nutrients and major ions. Out of nine stations, only one station discovered fish. Because the sampling was only done once, it is suggested that it be repeated at a different time because the research location is located in one of Greece's major catchments. Only three fish species were identified in the entire catchment area, indicating that more detailed studies are needed covering different surrounding areas.","PeriodicalId":32450,"journal":{"name":"IJEMS Indonesian Journal of Environmental Management and Sustainability","volume":"31 2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88974648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two research questions and two null hypotheses guided the study. A descriptive survey research design was adopted for the study. The study was conducted in FCT Abuja and Niger State, Nigeria. A total of 181 respondents consisting of 20 contractors, 71 builders and 90 tradesmen with 43 items structured questionnaire were used. The internal consistency of the questionnaire was determined using Cronbach alpha method and coefficients of A ꞊ 0.889 & B ꞊ 0.727 respectively. Weighted mean and standard deviation were used to analyze the research questions while ANOVA was used to test the null hypotheses at 0.05 level of significance. The findings of the study revealed that the respondents agreed with that of the safety facilities were utilized by the construction site worker while some were not complied. This implies that, safety facilities needs to be utilized in building construction. The findings revealed that there was significant difference in the mean ratings of the responses of the three groups of respondents (20 contractors, 71 builders and 90 tradesmen) as regard the of safety facilities. Similarly, there was no significant difference in the man ratings of the respondents as regards the extents of utilizing safety facilities in building construction sites. It was therefore recommended among others that contractors, builders and tradesmen require appropriate training/induction regularly on the use of safety facilities in building construction site base on their peculiarities. There should be appropriate information concerning the use personal protective equipment (PPE) at work to prevent accident from site.
