<p>The present study refers to biochar production, its application to soil with or without combining it with compost, as well as its effect on tomato (Solanum Lycopersicum L.) cultivation. The feedstock selected for biochar production was a mixture of primary and secondary sewage sludge, which had previously been anaerobically digested and thermally dehydrated. Sewage sludge pyrolysis was conducted at 300 °C. The produced biochar was initially characterized and subsequently applied to soil, in order to study its effect on Solanum Lycopersicum L. cultivation. Pot trials which included four treatments, each comprising of three replicates, were carried out during a period of three months, using pots with a 10 kg capacity. More specifically, the following treatments were studied: i) Control (soil without biochar addition), ii) soil with biochar at a rate of 2% w/w (BC-SS), iii) soil with compost at a rate of 2% w/w (Compost), and iv) soil with a mixture of biochar and compost at a total rate of 2% w/w (BC-SS+Compost). The aim of the study was to examine whether sewage sludge biochar with or without compost affects: a) the dry weight and morphological characteristics of the plant, b) the concentrations of macronutrients, micronutrients and heavy metals in aboveground and belowground plant tissues, c) soil properties, including nutrients and heavy metals.</p><p>With biochar application a number of soil properties exhibited substantial improvement. Specifically, significant increases were noticed for TOC (67% - 85% increase), NO<sub>3</sub>–N (55% increase) and ΝΗ<sub>4</sub>–Ν (145% increase). Moreover, biochar with or without compost, substantially improved plant growth (25% – 34% increase in the first 40 days), and led to a significant increase of the dry weight of aboveground and belowground plant tissues. Heavy metal concentrations in plant tissues were quite low. Specifically, traces of Cr, Ni and Co were found only in plant roots, while Si was present in plant roots and stems. As, Mo and Pb were present in all plant tissues, albeit without exceeding the permissible levels established for vegetables. Finally, no traces of Hg, Se and Cd were found in any of the tissues.</p><p>Generally, sewage sludge biochar addition to soil, with or without compost, improved soil characteristics and increased plant yield. Moreover, heavy metal concentrations within permissible levels do not raise any concerns regarding safe consumption of tomato fruits.</p><p> </p>

Sewage sludge application in agriculture is the simplest method of its management. Its content of organic and inorganic toxic components is a barrier to such management. Particular attention should be paid to the content of heavy metals whose presence in sewage sludge and later in soil poses hazard for plants, animals and people. The investigations aimed to determine the effect of vermicomposts obtained from tannery sludge on development of the root system and biomass of shoots as well as heavy metal concentrations in these organs. In the first year after the vermicomposts application their effect on the maize biomass increase was equal to the farmyard manure treatment but significantly worse than the mineral fertilization. The consecutive fertilizer effect of vermicomposts of tannery sludge ted on the increase in biomass of the shoots and roots of winter rape, sunflower and oats was comparable with the farmyard manure effect but notably better than the mineral fertilization. Heavy metal concentrations in individual plants were diversified; in the plants from vermicompost treatment they were as a rule lower than in the plants from mineral or farmyard manure treatment. Absorbed heavy metals accumulated primarily in the root systems, whereas the extremely high chromium content in vermicomposts did not cause its excessive accumulation in the cultivated plants.

Heavy metal pollution was reported in commercially valuable and edible pigeon (Columba livia, Gmelin 1789) of Bangladesh. The concentrations of As, Pb, Cd, Cr, Zn, and Cu were investigated in the muscle, intestine, kidney, gizzard and liver. For this 60 C. livia were selected from five locations to assess the degree of pollution by heavy metals in pigeon. Significant differences in heavy metal concentrations were observed among different tissues, but not among the locations. The ranges of the measured concentrations (?g/g dry weight) in the tissues of C. livia were as follows: arsenic: (0.01–0.04), (0.02–0.04), (0.02–0.08), (0.02–0.04) and (0.03–0.07); lead: (0.21–0.56), (0.07–1.64), (0.62–1.97), (0.41–0.79) and (1.47–5.75); cadmium: (0.01–-0.05), (0.13–0.97), (0.53–1.85), (0.32– 0.78) and (0.22–2.41); chromium: (0.25–1.93), (1.18–5.90), (1.59–4.40), (1.15–1.65) and (1.38–8.36); zinc: (73.22–256.56), (95.62–130.75), (19.87–67.18), (108.99–124.77) and (159.80–280.76); copper: (3.44–7.64), (5.30–17.50), (8.72–16.55), (1.19–34.42) and (26.09–43.60) in the muscle, intestine, kidney, gizzard, and liver, respectively. This research showed that the liver appeared to be the main storage site of heavy metals, while the muscle had the lowest levels of the analyzed metals. The concentrations of metal in the muscles were not found to exceed the acceptable level for human consumption.

Abstract Municipal leaves, sewage sludge, and street sand were composted by a modified Beltsville aerated pile technique. Rooted cuttings of Aster novi-belgii L. ‘Peter Harrison,’ Gaura Lindheimeri Engelm. & A. Gray and Sedum purpurem (L.) Link ‘Autumn Joy’ were grown for 4 months in 2 1 (2 qt) containers filled with media containing 0, 10, 30, 60, 80 and 100 (percent by vol) compost. The medium with 0% compost contained loamy sand topsoil, peat, sand and Styrofoam pellets (1:5:2:2 by vol). The pH of all media was between 6.0 and 7.0. Half the containers in each treatment received liquid fertilization in mid-season and half did not. Leachate from the containers was collected at monthly intervals and analyzed for the heavy metals Cd, Cr, Cu, Mn, Ni, Pb and Zn to determine their potential for leaching. Growth of perennials was equal or greater in all media containing compost, compared to the medium containing no compost. Liquid fertilizer further improved growth. Adding compost increased media aeration, available plant nutrients and heavy metals and decreased moisture retention and bulk density. Heavy metal concentrations in leachate were low, probably due to the near neutral media pH, and not likely to pose an environmental risk.

This study was conducted to estimate the concentration of selected heavy metals such as chromium (Cr), manganese (Mn), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) as well as the possible risk to consumer health from the flesh of three wild and cultured fishes (Labeo rohita, Mystus cavasius, and Heteropneustes fossilis) collected from the Meghna river, Narayangonj and Rajoir fish farm, Madaripur district respectively. Heavy metal concentrations were determined using Atomic Absorption Spectrometric method. The average concentration of heavy metals were found in the wild fish samples in the range as Cr (0.295-1.647), Mn (0.900-1.294), Ni (0.063-0.198), Cu (0.179-0.529), Zn (5.487-8.343), Cd (0.004-0.009) and Pb (0.193-0.290) mg/kg dry weight while in the cultured fish samples in the range as Cr (0.043-0.315), Mn (0.975-2.36), Co (BDL), Ni (0.005-0.095), Cu (0.238-0.978), Zn (5.487-8.305), Cd (0.004-0.009), and Pb (0.238-0.286) mg/kg dry weight respectively. The hierarchy of mean concentration of heavy metals in wild fishes was Zn> Mn> Cu> Pb> Cr> Ni > Cd and in the cultured fishes, the order was found Zn> Mn> Cr> Pb> Cu> Ni > Cd. The present study showed that the wild fish accumulated higher concentration of heavy metals in their muscles than the cultured fish. The analyzed Ni, Cu, Zn, Cd, and Pb were below the allowable level specified by international agencies (FAO, WHO, EU, CE, USEP). In order to assess the human health risk, the Target Hazard Quotient (THQ), Hazard Index (HI), and Target carcinogenic Risk (TR) were calculated. The TR values suggested that the fishes posed low to moderate carcinogenic risk from Cr, Ni and Cd. Consequently, continuous and excessive consumption of these fish species over a lifetime will increase the possibility of causing cancer. Bangladesh J. Zool. 49 (2): 189-203, 2021

Dewatered Sewage Sludge

Two forms of biosolids, with and without lime, were applied to acid soils at 2 sites growing wheat and triticale in central New South Wales. The forms of biosolids used were dewatered sewage sludge cake, and N-Viro Soil which is a lime-amended sewage sludge. Dewatered sewage sludge cake was applied at rates of 0, 6, 12 and 24 dry Mg/ha, and N-Viro soil at 0, 1.5, 3.0 and 4.5 dry Mg/ha. The soil was sampled and analysed at 2 points in time to determine the effect of the biosolids on heavy metal concentrations. Vegetative plant material and grain were also analysed for heavy metal and organo-chlorine pesticide levels. Zinc and copper concentrations increased significantly with the addition of biosolids, especially with the highest rates of dewatered sewage sludge cake. However, all soil heavy metals were below the maximum allowable soil contaminant concentrations set by Environment Protection Authority, NSW. Cereal species, the addition of lime, and biosolids each affected heavy metal concentrations in plant material, but the responses differed between sites. Also, the changes in heavy metal concentrations in plant material were smaller and less consistent than the changes in soil heavy metal concentrations. The maximum heavy metal concentrations in grain were all below the maximum permitted concentrations of Food Standards Australia New Zealand. There were no detectable changes in the levels of organo-chlorine pesticides in the grain.

The heavy metal concentration (e.g., Mn, Zn, Pb and Ni) were determined in soft tissues and shells of freshwater mussels (Lamellidens marginalis) at the various sites of Dhanmondi lake, Dhaka, Bangladesh between the period April, 2010 and March 2011. The heavy metal concentrations in shells and soft tissues of freshwater mussels were tended to vary significantly among sampling points and seasons in Dhanmondi Lake. Distribution of heavy metals in shell and soft tissue of Lamellidens marginalis followed the order Mn>Zn>Pb>Ni, respectively. According to the t-test, level of manganese, zinc and lead under investigation between shell and tissue showed statistically significant differences [Mn: t=-11.387; df=16; P=0.000; Zn: t=-2.590; df=16; P=0.020 and Pb: t=-2.8679; df=16; P=0.011].

The effect of ammonium chloride, sodium butyrate, sodium propionate, and the heavy metals nickel, zinc, and copper on methanogenesis by pure cultures of Methanospirillum hungatei, Methanosarcina barkeri, Methanobacterium thermoautotrophicum, and Methanobacterium formicicum at pH 6.5 was studied. The latter three strains were resistant to > 60 g/L of the volatile fatty acids and to > 10 g/L of NH3 N. Methanospirillum hungatei was somewhat more sensitive with 50% inhibition of methanogenesis occurring at 4.2 g/L NH3 N, 27 g/L butyrate, and 41 g/L propionate. All strains were very sensitive to both copper (1–5 mg/L) and zinc (1–10 mg/L), but much more resistant to nickel. Zinc and copper concentrations 30 to 270 times higher were required to cause inhibition of Msp. hungatei incubated in sewage sludge compared with buffer, indicating a strong protective environment was afforded the methanogens against heavy metal toxicity in the sludge.

Plant Pollution

This paper reports the concentration of heavy metals (Cr, Cu, Zn, Cd and Pb) in the soils and rices surrounding the abandoned rural waste dumping sites in Ningbo. Igeo (geoaccumulation index) was calculated to assess the contamination degree of heavy metals in soils. The mean contents of Cr, Cu, Cd, Zn and Pb of soils were 33.3, 24.1, 1.5, 118.9 and 45.6 mg/(kg DW) (dry weight), respectively. All of them were much higher than that of the reference value (i.e. CK), but there were no coherent trend of the metal contents within 1-120m distance from the dumping site. Igeo of heavy metals reveals the order of Cd>Cu>Cr>Pb>Zn, and the contamination assessment of soils using Igeo indicate the moderate Cd pollution, while the soils were unpolluted-moderately overall by Cr, Cu, Zn as well as Pb. The heavy metal contents in root, stem & leaf and rice grains were all remarkable higher than that of the CK at 20-120 m distances, and the heavy metal contents in root were evidently much higher than other plant parts, while those in rice grain were lowest, indicating the great bioaccumulation trend of heavy metals. Although the metal contents in the rice grain were within the legislation limit, its bioaccumulation trend of heavy metals was remarkable, whose contents were 4.38-fold for Cr, 1.76-fold for Cu, 1.28-fold for Zn, 2.67-fold for Cd and 3.03-fold for Pb higher than that of reference value, respectively. Finally, we proposed a decentralized in-situ restoration approach for the dumping sites.
