JOURNAL FREE ACCESSThe logic concept underlying the transferable development rights or the transfer of development rights (TDR) is that title to real estate is not a unitary right, but rather it may be compared to a "bundle of individual rights, " each one of which may be separated from the rest and transferred to someone else, leaving the original owner with all other rights of ownership. Planner and lawyers in the United States have begun to experiment with a variety of techniques to use TDR for purposes of land use regulation. This paper shows how TDR preserves environmental resources (for example, farmland) and equalizes the gains from development between developed land and undeveloped land, and compares TDR markets with other methods for preservation of environmental resources.View full abstractDownload PDF (1202K) -

JOURNAL FREE ACCESSA new process was developed for removal and recovery of phosphorous in wastewater which cause the eutrophication of lake, bay and inland sea. A new superior adsorbent was prepared from activated alumina with adhering aluminum sulfate, and its adsorption capacity and rate were obtained under various conditions. The best conditions for desorption and generation of the spent adsorbent were obtained, and recovering methods of phosphorous and aluminum from the waste desorbed liquid were also developed. Furthermore, feasibility of this process was confirmed by an application test for tertialy treatment of sewage, and the costs were estimated under practical conditions.View full abstractDownload PDF (1793K) -
-Effect of Pollutant Load Levy Imposed on Emission Sources-Hidefumi IMURA1988 Volume 1 Issue 2 Pages 115-125

JOURNAL FREE ACCESSEnvironmental quality in terms of SOx in the atmosphere has been drastically improved in Japan since 1970s. The emission reduction achieved in the 1970s can be attributed to the strict regulation enforced by the central and local governments. The reduction in the 1980s, however, was realized under an economic and energy condition very different from that in the 1970s. While the Japanese economy underwent drastic structural changes in favor of energy saving, a pollutant load levy system was inaugurated in 1974 based on the Pollution-Victims Compensation Law, and the ever increasing rate of levies imposed on emission sources created an economic incentives to reduce emisson level beyond the regulatory standards. The incentive effect was particularly significant in the regions designated by the law, as is discussed in this paper. An economic model is presented to estimate the emission reduction owing to the decreasing demand of heavy oil and the increasing rate of pollutant load levy imposed on emission sources of sulfur oxides. Basic mechanisms of the emission reduction achieved in the 1980s are explained by this model through comparison of the designated and the non-designated regions.View full abstractDownload PDF (1653K) -

JOURNAL FREE ACCESSToxicity of copper, cadmium and cobalt on the growth of blue-green algae Microcystis aeruginosa K3A, Microcystis viridis (toxic algae). Anabaena affinis and green algae Chlorella ellipsoidea was determined in the liquid medium. The EC50 (effective concentration, 50% inhibition of the specific growth rate of control) of copper for M. aeruginosa K3A, M. viridis, A. affinis, C. ellipsoidea were 0.019 μM, 0.023 μM, 0.018 μM and 0.58 μM, respectively. Copper showed the severest toxicity to the growth of these algae compared with cadmium and cobalt. The sensitivity to copper of three species of the blue-green algae was 30 times higher than that of the green algae C. ellipsoidea. Chelating agents such as EDTA and EGTA showed the strong reducing effect on the copper toxicity while NTA had the weak reducing effect. Copper concentration in the surface water of Lake Kasumigaura was 0.017 μM, which was the almost same to the value of EC50 for blue-green algae. However, the EC50 of copper for M. aeruginosa K3A in the lake water was found to be 3 times larger than in the liquid medium. From these facts, natural ligands in the lake water is assumed to stimulate the growth of blue-green algae to make algal bloom.View full abstractDownload PDF (919K) -
