“…The silicon level showed a higher level in group (2) (2.22) and the lower level observed in group (8 ) that treated with Sand + Break dust + raw rice husks its level reached to (0.14). The arsenic level showed a higher level in control group (0.0013), group 1 (0.0003), group (3) that treated with Sand + Biochar saw dust + Biochar saw dust as its level reached to (0.0003) and the lower level reached to (0) Our results agreed with those of Yang et al, 2014), where they observed that, the addition of biochar to fish ponds reduce the level of heavy metals in fish production ponds.…”

“…Using biochar as a soil fertilizers improved the plant growth, soil fertility with reduction of the heavy metal pollution in the agriculture water with and its usage in aquaculture ponds improved the fish growth than the non-fertilized soil or aquaculture ponds with biochar (Schmidt, 2014). Yang et al (2014) suggested that using of a low-cost Alternanthera philoxeroides biochar (APB) adsorbent for heavy metals contaminated water treatment may have great ecological and environmental significance as it reduces the level of heavy metals such as lead, mercury, copper and other harmful heavy metals. Lim et al (2014) observed that the using of biochar in aquaculture may potentially alter nitrous oxide (N 2 O) emission by affecting ammonia-oxidizing and nitrification bacteria, which is determined by the application rate of biochar in soil and water.…”

Biochar is commonly used for absorption of heavy metals in the soils and water and so decreasing its level in fish meat with improvement of growth performance, productivity and hatchability as well as immunity of the fish against different fish diseases. The present work was conducted a fish farm is Metobase area in Kafr El-Sheikh governorate during season 2014. The period extended from January to May at the department of fish production Fac. of Agric. Saba Basha, Alexandria University. The biochar was prepared by burning of the rice bran at 300 o C using circular cylinder rotated by anaerobic motors. In our investigation, a total number of 162 broodstock of Oreochromis niloticus fish that were collected from private fish farm at Kafr El-Sheikh governorate, Egypt. The enhancement of aeration of aquaculture occurred by air blowers and agriculture machine, and the water column of ponds in both was about 1.5m. The aim of this study is to investigate the importance of biochar in growth performance and production efficiency of Nile tilapia as well as protective effects of heavy metal pollution in the aquaculture environment, product of fish and finally the histopathological alterations. Our results concluded that, the addition of biochar to the fish production ponds decrease the level of heavy metals and reduced its accumulation in fish organs especially the saw dust biochar, followed by rice husk biochar.

“…) was selected as a representative heavy metal as it is one of the most common contaminants in water and soil and represents serious concerns to human health and environment pollution [15], and demonstrated the highest sorption to Salisbury biochar in a previous study [5]. This study aims to investigate: (1) the impact of biochar on the mobility of Pb 2+ in kaolin; (2) the impact of biochar on the speciation of Pb 2+ in kaolin; (3) the short-term time dependence of the two impacts.…”

Salisbury biochar (produced from British broadleaf hardwood) with two different particle sizes (≤ 2 mm and ≤ 0.15 mm) was applied on a kaolin with three different lead (Pb 2+ ) contamination levels (50 mg/kg, 300 mg/kg and 1000 mg/kg) at the dosage of 1% in w/w. The short-term impact of biochar on the mobility and speciation of Pb 2+ in the kaolin was investigated using attenuation periods of 1, 7and 28 days. This paper suggests the inefficiency of biochar treament on heavy-metal contaminated clay-rich soils. Therefore a laboratory treatablity study with respect to the soil type may be crucial when large-scale biochar applications in heavy-metal associated soil remediation are evaluated.

“…However, the mowed rootstock needs to be disposed immediately; otherwise, AP will spread further. The main methods of physical control are manual removal and disposal, but this approach creates secondary environmental problems, such as the release of pathogens and methane (Yang et al 2014). Moreover, in situ stubble burning of AP is now banned because of the smoke and other hazards (Abouziena and Haggag 2016).…”

Activated carbons (ACs) were prepared from Alternanthera philoxeroides (AP) by K2CO3 one-step mixing activation. The effects of the mixing mass ratio of K2CO3 to AP, activation temperature, N2 flow rate, and period on the yield and specific surface area of ACs were investigated. The results showed that the surface area and pore volume of ACs were closely related to activation conditions and that the activation temperature was the main factor influencing the surface area and pore volume. The activation conditions only had a slight effect on the yield of ACs, which varied between 13.5% and 19.5%. The surface area of 1799.8 m 2 /g was obtained at a K2CO3 to AP mass ratio of 2:1, activation temperature of 900 °C, activation time of 2 h, and N2 flow rate of 60 cm 3 /min. The surface morphology of ACs were characterized with scanning electron microscopy (SEM), and the recovered K2CO3 was characterized with powder X-ray diffractometry (XRD). The SEM images of the ACs also showed that the activation temperature had an obvious effect on the porous structure.
