Polyalthia longifolia is a plant that used as a roadside in Purwokerto. This study aimed to determine the ability of the plant P. longifolia in the air and accumulate Pb anatomic response to the Pb concentration in the leaves of P. longifolia. The methods of research used survey methods. Roadside plant leaf samples were taken by purposived sampling at six locationsmain street in Purwokerto, there are Jenderal Soedirman, Dr. Soeparno, HR. Bunyamin, Commisioner Bambang Soeprapto and Gerilya. The independent variable was the ambient air Pb and Pb leaf was the dependent variable. The main parameters investigated were air Pb concentrations, Pb leaves, stomata anatomical characters and thick mesophyll tissue. Parameter support was the traffic density. The results showed that the highest concentration of Pb in the air with a concentration of 0.1020 μg/m3 per hour on Gerilya street and the lowest in DR. Soeparno street with concentrations of 0.0048 μg/m3 per hour, it can be concluded that an ambient air Pb in six study sites are still under ambient air quality in Central Java, which is 2 μg/m3 per 24 hours. Leaf Pb concentration was highest in HR. Bunyamin street with a concentration of 0.4980 ± 0.004 ppm and lows in the DR. Soeparno street with concentrations of 0.2786 ± 0.008 ppm. Pb accumulated in leaves affects the density, length, and width of stomata and mesophyll tissue thickness P. longifolia. Pb concentrations was not correlate with the leaf Pb concentration P. longifolia. Pb concentrations of leaves of P. longifolia is closely linked with decreasing density of stomata and mesophyll tissue thickness but not related to the length and width of the stomata.

This study aimed at assessing the influence of vehicle traffic on spatial variation of ozone (O3) and its vehicular emission precursors in the air of Port Harcourt city. Sampling was carried out in ten (10) sites, eight (8) located within the high traffic density area (study sites) and two (2) located within the very low traffic density area (reference sites). The precursor pollutants measured were nitrogen dioxide (NO2), carbon monoxide (CO) and volatile organic compounds (VOCSs). Ozone and the precursor pollutants were measured in situ using AeroQUAL 500 series portable ambient air analyzer while traffic flow survey was achieved by direct counting. Measurements were carried out at morning, evening and off-peak traffic periods respectively. The mean concentrations of ozone and the precursor pollutants were significantly higher (p = 0.05) in the study sites than in the reference sites. Mean concentrations were higher at peak traffic periods than at off-peak traffic periods except for ozone that was higher at off-peak than at morning peak. There was significant correlation between traffic density and each of the pollutants including ozone. The spatial variability in concentration of pollutants was influenced by vehicular traffic. VOCs and NO2 levels were higher than the National Ambient Air Quality Standard (NAAQS) limit of 0.05 ppm and 0.04 – 0.06 ppm respectively, O3 concentration was below the standard limit (0.06 ppm) but was at the verge of exceeding. Traffic emission within the city was significant and could be mitigated through regular monitoring and control.

The objectives of this experiment were to determine the effects of graded dietary lead (Pb) concentrations on body weight and Pb concentrations in blood, hair, soft tissues, and urine from pigs and to generate equations for estimating daily Pb intake. Sixteen barrows with initial body weight 36.3 kg (standard deviation = 2.3) were allotted to four dietary treatments that consisted of graded supplemental Pb concentrations (0, 10, 25, and 250 mg/kg of diet). Daily feed allowances for each pig were 1 kg for first two weeks and 2 kg for last two weeks. The hair and blood of pigs were collected on d 14 and 28. At the end of experiment, the pigs were euthanized, and the liver, kidneys, muscle, and urine samples were collected. The prediction equations for estimating daily Pb intake of pigs were generated using Pb concentration of blood, hair, tissues, or urine as an independent variable. The Pb concentrations in the blood, hair, liver, kidneys, muscle, and urine linearly increased (P < 0.01) with increasing dietary Pb concentrations. There were quadratic effects (P < 0.05) of increasing dietary Pb concentration on Pb concentrations in the blood, hair, and muscle. There were highly positive correlations between dietary Pb concentration and Pb concentrations in the blood, hair, liver, kidneys, muscle, and urine (r > 0.83;P < 0.01). The equations were significant (P < 0.01) and showed highr2(>0.83), except the equation using Pb concentration in the muscle as an independent variable. In conclusion, the dietary Pb concentration was highly correlated with Pb concentrations in the blood, hair, soft tissues, and urine of pigs. The total dietary Pb intake can be estimated from the Pb concentrations in the blood, hair, soft tissues, or urine for pigs.

Increases in mean temperature affect the diversity and abundance of wild bees in agricultural ecosystems. Pollinator community composition is expected to change along an elevational gradient due to differences in the daily ambient temperature. This study investigated the diversity and abundance of wild bees in an agricultural area along an elevational gradient in Central Java, Indonesia. Wild bees were collected using a sweep net in 40 green bean (Phaseolus vulgaris) cultivation sampling locations at seven different elevations (8, 108, 224, 424, 644, 893, and 1017 m above sea level). Species diversity was determined using the Shannon–Wiener diversity index. We identified 932 individuals from 8 species of wild bee belonging to 3 families. The family Apidae was predominant, with 6 species, while only 1 species was found from each of Megachilidae and Halictidae. Across the study sites, diversity increased with increasing elevation (H′= 1.4,D= 0.25, andE= 0.78 at low elevation toH′= 2.04,D= 0.13, andE= 0.96 at high elevation), and higher numbers of species were found at middle and high elevations. Species richness and abundance increased linearly with increasing elevation, and species diversity was highest at middle elevations.
