2006年8月至9月，作为第二次德克萨斯州空气质量研究的一部分，使用移动的微型差分光学吸收光谱仪对休斯顿船舶通道和德克萨斯城工业区的NO2和SO2排放量进行了量化。从休斯顿船舶通道和得克萨斯城工业区测得的NO2排放量分别为2542和452 kg h（-1），分别产生NOx排放量的70%和43%，分别高于报告的库存值。从休斯顿船舶通道地区的量化二氧化硫排放量为1749公斤小时（-1），被发现是34%以上的清单中报告的值。NO2和SO2排放量的短期变化被发现在休斯顿船舶通道。2006年8月31日，在连续三次测量期间，在HSC探测到一个羽流，得出的甲醛通量为481千克·小时（-1）。这一事件主要归因于光化学生产。
In August-September 2006, as part of the Second Texas Air Quality Study, NO2 and SO2 emissions from the Houston Ship Channel and Texas City industrial areas were quantified using mobile mini-differential optical absorption spectroscopy instruments. The measured NO2 emissions from the Houston Ship Channel and Texas City industrial areas were 2542 and 452 kg h(-1), respectively, yielding NOx emissions 70% and 43%, respectively, above the reported inventory values. Quantified SO2 emissions from the Houston Ship Channel area were 1749 kg h(-1) and were found to be 34% above the values reported in the inventory. Short-term variability of NO2 and SO2 emissions was found at the Houston Ship Channel. On 31 August 2006, a plume was detected at the HSC during three consecutive measurements, yielding a HCHO flux of 481 kg h(-1). This event has been mainly attributed to photochemical production.
